To install Flutter and Dart plugins, follow the Setup an editor instructions.
Updates are sent out regularly. When an update is available, you should be prompted in your IDE.
You can manually check for updates:

WHEN CREATING A NEW APP, Flutter IDE plugins require an organization name in reverse-domain order. For example, com. example. This is the package name for Android and the Bundle ID for iOS. It is best to indicate these details if you plan to release the app. These cannot be modified once the app has been removed. Uniqueness is essential for your organization's name.
To create a Flutter project that contains existing Flutter source codes:

Click New Project in the Welcome Window or New Project in the main IDE window.
The Flutter plugin allows you to perform code analysis.
Notice: There are a few ways to debug your app.

Below are instructions for Android Studio and IntelliJ features. For more information about launching DevTools, please see Running DevTools From Android Studio in our DevTools documentation.
Flutter projects should be open in the IDE. You will see a series of Flutter-specific buttons to the right of the toolbar.
Note that Flutter cannot detect any iOS or Android devices connected to it if the Run and Debug buttons have been disabled and no targets are specified. To proceed, you must click an instrument or start a simulation.
Flutter's best-in-class developer cycle allows you to see the effects of your changes almost immediately with the Stateful hot reload feature. See Hot fill for details.
To see the performance data, including widget rebuild information, open the app in Debug mode and then use View> Tools > Flutter Performance.
Click Show widget rebuild info to see stats about rebuilt devices and how often. In the second column to the right, you will see the exact number of rebuilds for this frame. A yellow spinning circle indicates a high amount of rebuilds. The queue to your right displays how many times a widget has been rebuilt since it was last seen on the screen. A solid grey circle will display for devices that haven't been rebuilt. A grey spinning circle shows otherwise.
This screenshot shows how the app was designed to provide poor performance. The rebuild profiler will give you an indication of what might be causing poor performance. The widget rebuild profiler is not an instrument that can diagnose poor performance.
This feature will alert you when widgets rebuild. You might not be aware of it if you only look at the code. If devices start rebuilding in unexpected ways, this is a sign you need to refactor your code. Split extensive build methods into multiple widgets.
This tool will help you to debug at most four everyday performance issues. A single StatefulWidget builds the screen or significant parts, resulting in unnecessary UI construction. Divide the UI into smaller widgets using more petite build() operations.

Rebuilding widgets that are not visible on screen is possible. This could happen when a ListView is nestled in a Column that extends beyond the screen. The RepaintBoundary may not be set for a list that extends beyond the screen, which can cause the entire list to be redrawn.
An AnimatedBuilder's build() function draws a subtree, which does not require animation. This can lead to unnecessary rebuilds of static objects.
Unnecessarily high widget trees are places for Opacity widgets. An Opacity animation can be created by manipulating the Opacity property of the Opacity Widget, which causes the device and its subtrees to rebuild.
To navigate to the source line where the widget was created, click on the line in Table. The code pane displays spinning icons as the code runs. This helps you see which rebuilds are taking place.
It is possible to have multiple rebuilds without a problem. It would be best not to worry about excessive rebuilds unless you had run the app in profile mode before and confirmed that it is performing poorly.
Remember that widget rebuild information can only be found in a debug. You can test the app's performance using a profile build. However, you can debug performance issues with a debug version.
Live templates can be used to speed up the process of entering code structures. These templates can be invoked by entering their prefix and selecting them in the code completion window.

The following templates are available in the Flutter plugin:
You can also create custom templates in Settings> Editor > Live Templates.
Hot reload is done by inserting new source code files into Dart VM (Virtual Machine) running. This includes adding new classes, methods, and fields for existing courses and changing functions. Some code changes can't be hot reloaded.

These changes will allow you to restart your application without closing your debugging session. Do not click the Stop button to perform a hot restart. Instead, re-click either the Run button (if you are in a run session) or the Debug button (in a debug session), then shift-click on the 'hot load' button.
You need to set the Android SDK's location in IntelliJ IDEA to enable Android code editing.
