This page describes how to create a new Flutter app from templates, run it,and experience “hot reload” after you make changes to the app.
Hi, I have an issue I downloaded android studio, download flutter 1.22 stable version and unzip it, added flutter and dart plugin in android studio, ran flutter doctor, and I got flutter and dart not installed, so I changed the channel to dev, by typing 'flutter channel dev', and then upgrade it, and then run flutter doctor again, now I have flutter version 1.23.0-18.pre with flutter and dart. Under Language & Frameworks choose Flutter and find Flutter SDK path field. Your flutter SDK path is two step above in the folder hierarchy relative to which which flutter command gave to you. Set it to the field you've found in step 1 of this header. Again click Apply & click save or ok.

How to setup Flutter on Android Studio? Flutter is an open source mobile app development SDK from Google, used to build beautiful Native Android and iOS apps with a single codebase.
Select your development tool of choice for writing, building, and runningFlutter apps.
Create the app
Do you want to run your Flutter app on the web? The web version of Flutter is available on the beta channel. To try it out, check out the Write your first Flutter app for the web codelab.
- Open the IDE and select Start a new Flutter project.
- Select Flutter Application as the project type. Then click Next.
- Verify the Flutter SDK path specifies the SDK’s location(select Install SDK… if the text field is blank).
- Enter a project name (for example,
myapp
). Then click Next. - Click Finish.
- Wait for Android Studio to install the SDK and create the project.
Note: When creating a new Flutter app, some Flutter IDE plugins ask for a company domain name in reverse order, something like
com.example
. The company domain name and project name are used together as the package name for Android (the Bundle ID for iOS) when the app is released. If you think that the app might be released, it’s better to specify the package name now. The package name can’t be changed once the app is released, so make the name unique.The above commands create a Flutter project directory called
myapp
thatcontains a simple demo app that uses Material Components.Tip: The code for your app is in
lib/main.dart
. For a high-level description of what each code block does, see the comments at the top of that file.Run the app
- Locate the main Android Studio toolbar:
- In the target selector, select an Android device for running the app.If none are listed as available,select Tools> Android > AVD Manager and create one there.For details, see Managing AVDs.
- Click the run icon in the toolbar, or invoke the menu item Run > Run.
After the app build completes, you’ll see the starter app on your device.
Try hot reload
Flutter offers a fast development cycle with Stateful Hot Reload,the ability to reload the code of a live running app withoutrestarting or losing app state.Make a change to app source,tell your IDE or command-line tool that you want to hot reload,and see the change in your simulator, emulator, or device.
- Open
lib/main.dart
. - Change the stringtoImportant: Do not stop your app. Let your app run.
- Save your changes: invoke Save All, or click Hot Reload .
You’ll see the updated string in the running app almost immediately.
Profile or release runs
Important: Do not test the performance of your app with debug and hot reload enabled.
So far you’ve been running your app in debug mode. Debugmode trades performance for useful developer features suchas hot reload and step debugging. It’s not unexpected tosee slow performance and janky animations in debug mode.Once you are ready to analyze performance or release yourapp, you’ll want to use Flutter’s “profile” or “release”build modes. For more details, see Flutter’s build modes.
Important: If you’re concerned about the package size of your app, see Measuring your app’s size.

The package name can’t be changed once the app is released, so make the name unique.Warning:If VS Code was running during your initial Flutter setup, you may need to restart it for VS Code’s Flutter plugin to detect the Flutter SDK.
Tip: The code for your app is in
lib/main.dart
. For a high-level description of what each code block does, see the comments at the top of that file.Run the app
- Locate the VS Code status bar (the blue bar at the bottom of thewindow):
- Select a device from the Device Selector area.For details, see Quickly switching between Flutter devices.
- If no device is available and you want to use a device simulator,click No Devices Send pictures to a phone from computer. and launch a simulator.Warning:You may not see Start iOS Simulator option when you click No Devices in VS Code. If you are on Mac then you may have to run following command in terminal to launch a simulator.In Android it is not possible to launch iOS simulator.
- To setup a real device, follow the device-specific instructions on theInstall page for your OS.
- Invoke Run > Start Debugging or press F5.
- Wait for the app to launch — progress is printedin the Debug Console view.
After the app build completes, you’ll see the starter app on your device.

- Get the Flutter SDK
- Android setup
System requirements
To install and run Flutter,your development environment must meet these minimum requirements:
- Operating Systems: Windows 7 SP1 or later (64-bit), x86-64 based
- Disk Space: 1.64 GB (does not include disk space for IDE/tools).
- Tools: Flutter depends on these tools being available in your environment.
- Windows PowerShell 5.0 or newer (this is pre-installed with Windows 10)
- Git for Windows 2.x, with theUse Git from the Windows Command Prompt option.If Git for Windows is already installed, make sure you can run
git
commands from the command prompt or PowerShell.
Get the Flutter SDK
- Download the following installation bundle to get the lateststable release of the Flutter SDK:For other release channels, and older builds, see theSDK releases page.
- Extract the zip file and place the contained
flutter
in the desired installation location for the Flutter SDK(for example,C:srcflutter
).
Warning: Do not install Flutter in a directory like
C:Program Files
that requires elevated privileges.If you don’t want to install a fixed version of the installation bundle, you can skip steps 1 and 2. Instead, get the source code from the Flutter repo on GitHub, and change branches or tags as needed. For example:
You are now ready to run Flutter commands in the Flutter Console.
Update your path
If you wish to run Flutter commands in the regular Windows console,take these steps to add Flutter to the
PATH
environment variable:- From the Start search bar, enter ‘env’and select Edit environment variables for your account.
- Under User variables check if there is an entry called Path:
- If the entry exists, append the full path to
flutterbin
using;
as a separator from existing values. - If the entry doesn’t exist,create a new user variable named
Path
withthe full path toflutterbin
as its value.
- If the entry exists, append the full path to
You have to close and reopen any existing console windowsfor these changes to take effect.
Note: As of Flutter’s 1.19.0 dev release, the Flutter SDK contains the
dart
command alongside the flutter
command so that you can more easily run Dart command-line programs. Downloading the Flutter SDK also downloads the compatible version of Dart, but if you’ve downloaded the Dart SDK separately, make sure that the Flutter version of dart
is first in your path, as the two versions might not be compatible. The following command (on macOS, linux, and chrome OS), tells you whether the flutter
and dart
commands originate from the same bin
directory and are therefore compatible. (Some versions of Windows support a similar where
command.)As shown above, the two commands don’t come from the same
bin
directory. Update your path to use commands from /path-to-flutter-sdk/bin
before commands from /usr/local/bin
(in this case). After updating your shell for the change to take effect, running the which
or where
command again should show that the flutter
and dart
commands now come from the same directory.To learn more about the
dart
command, run dart -h
from the command line, or see the dart tool page.Run flutter doctor
From a console window that has the Flutter directory in thepath (see above), run the following command to see if thereare any platform dependencies you need to complete the setup:
This command checks your environment and displays a report of the statusof your Flutter installation. Check the output carefully for othersoftware you might need to install or further tasks to perform(shown in bold text).
For example:
![Path Path](https://i.ytimg.com/vi/sqrrWguAXZk/maxresdefault.jpg)
The following sections describe how to perform these tasks andfinish the setup process. Once you have installed any missingdependencies, you can run the
flutter doctor
command again toverify that you’ve set everything up correctly.Note: If
flutter doctor
returns that either the Flutter plugin or Dart plugin of Android Studio are not installed, move on to Set up an editor to resolve this issue.Warning: The
flutter
tool uses Google Analytics to anonymously report feature usage statistics and basic crash reports. This data is used to help improve Flutter tools over time.Flutter tool analytics are not sent on the very first run. To disable reporting, type
flutter config --no-analytics
. To display the current setting, type flutter config
. If you opt out of analytics, an opt-out event is sent, and then no further information is sent by the Flutter tool.By downloading the Flutter SDK, you agree to the Google Terms of Service. Note: The Google Privacy Policy describes how data is handled in this service.
Moreover, Flutter includes the Dart SDK, which may send usage metrics and crash reports to Google.
Android Studio Flutter Sdk Path
Android setup
Note: Flutter relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Flutter apps in a number of editors; a later step discusses that.
Install Android Studio
- Download and install Android Studio.
- Start Android Studio, and go through the ‘Android Studio Setup Wizard’.This installs the latest Android SDK, Android SDK Command-line Tools,and Android SDK Build-Tools, which are required by Flutterwhen developing for Android.
Set up your Android device
To prepare to run and test your Flutter app on an Android device,you need an Android device running Android 4.1 (API level 16) or higher.
- Enable Developer options and USB debugging on your device.Detailed instructions are available in theAndroid documentation.
- Windows-only: Install the Google USBDriver.
- Using a USB cable, plug your phone into your computer. If prompted on yourdevice, authorize your computer to access your device.
- In the terminal, run the
flutter devices
command to verify thatFlutter recognizes your connected Android device. By default,Flutter uses the version of the Android SDK where youradb
tool is based. If you want Flutter to use a different installationof the Android SDK, you must set theANDROID_SDK_ROOT
environmentvariable to that installation directory.
Set up the Android emulator
To prepare to run and test your Flutter app on the Android emulator,follow these steps:
- EnableVM accelerationon your machine.
- Launch Android Studio, click the AVD Managericon, and select Create Virtual Device…
- In older versions of Android Studio, you should insteadlaunch Android Studio > Tools > Android > AVD Manager and selectCreate Virtual Device…. (The Android submenu is only presentwhen inside an Android project.)
- If you do not have a project open, you can choose Configure > AVD Manager and select Create Virtual Device…
- Choose a device definition and select Next.
- Select one or more system images for the Android versions you wantto emulate, and select Next.An x86 or x86_64 image is recommended.
- Under Emulated Performance, select Hardware - GLES 2.0 to enablehardwareacceleration.
- Verify the AVD configuration is correct, and select Finish.For details on the above steps, see ManagingAVDs.
- In Android Virtual Device Manager, click Run in the toolbar.The emulator starts up and displays the default canvas for yourselected OS version and device.
Web setup
Flutter has support for building web applications in the
stable
channel. Any app created in Flutter 2 automaticallybuilds for the web. To add web support to an existing app, followthe instructions on Building a web application with Flutter when you’ve completed the setup above.Next step
