Running and Debugging:

In Android studio & IntelliJ:

You can debug your app in a few ways.

• Using DevTools, a suite of debugging and profiling tools that run in a browser and include the Flutter inspector.

• Using Android Studio's (or IntelliJ's) built-in debugging features, such as the ability to set breakpoints.

• Using the Flutter inspector, directly available in Android Studio and IntelliJ.

• Running and debugging are controlled from the main toolbar:

  

If the Run and Debug buttons are disabled, and no targets are listed, Flutter has not been able to discover any connected iOS or Android devices or simulators. You need to connect a device, or start a simulator, to proceed.

In Visual Studio:

You can debug your app in a couple of ways.

• Using DevTools, a suite of debugging and profiling tools that run in a browser.

• Using VS Code's built-in debugging features, such as setting breakpoints.

• Start debugging by clicking Run > Start Debugging from the main IDE window, or press F5.

• When a Flutter project is open in VS Code, you should see a set of Flutter specific entries in the status bar, including a Flutter SDK version and a device name (or the message No Devices):

  

• The Flutter extension automatically selects the last device connected. However, if you have multiple devices/simulators connected, click device in the status bar to see a pick-list at the top of the screen.

• Select the device you want to use for running or debugging.

Run app with breakpoints:

In Android studio & IntelliJ:

1. If desired, set breakpoints in your source code.

2. Click the Debug icon in the toolbar, or invoke Run > Debug.

   • The bottom Debugger pane shows Stack Frames and Variables.

   • The bottom Console pane shows detailed logs output.

   • Debugging is based on a default launch configuration. To customize this, click the drop-down button to the right of the device selector, and select Edit configuration.

In Visual Studio:

1. If desired, set breakpoints in your source code.

2. Click Run > Start Debugging. You can also press F5. The status bar turns orange to show you are in a debug session.

   

   • The left Debug Sidebar shows stack frames and variables.

   • The bottom Debug Console pane shows detailed logging output.

   • Debugging is based on a default launch configuration. To customize, click the cog at the top of the Debug Sidebar to create a launch.json file. You can then modify the values.

     Run app in debug, profile, or release mode in VS code

     Flutter offers many different build modes to run your app in. You can read more about them in Flutter's build modes.

     1. Open the launch.json file in VS Code.

        If you don't have a launch.json file:

        1. Go to View > Run.

           You can also press Ctrl / Cmd + Shift + D

           The Run and Debug panel displays.

        2. Click create a launch.json file.

     2. In the configurations section, change the flutterMode property to the build mode you want to target.

        For example, if you want to run in debug mode, your launch.json might look like this:

        json

         "configurations": [
           {
             "name": "Flutter",
             "request": "launch",
             "type": "dart",
             "flutterMode": "debug"
           }
         ]
        

        content_copy

     3. Run the app through the Run panel.
