How can I remove the debug banner in Flutter?

I am using flutter screenshot and I would like the screenshot not to have a banner. Now it does have.

Note that I get not supported for emulator message for profile and release mode.

Solution 1:^[1]

Outdated

If you are using Android Studio, you can find the option in the Flutter Inspector tab ? More Actions.
Or if you're using Dart DevTools, you can find the same button in the top right corner as well.

Solution 2:^[2]

Well, this is the simple answer you want.

MaterialApp(
  debugShowCheckedModeBanner: false
)

CupertinoApp(
  debugShowCheckedModeBanner: false
)

But if you want to go deep with the app (want a release APK file (which doesn't have a debug banner) and if you are using Android Studio then go to Run ? Flutter ? Run 'main.dart' in Release mode.

Solution 3:^[3]

If you are using IntelliJ IDEA, there is an option in the Flutter Inspector to disable it.

Run the project:

When you are in the Flutter Inspector, click or choose "More Actions."

When the menu appears, choose "Hide Debug Mode Banner":

Solution 4:^[4]

There is also another way for removing the "debug" banner from the Flutter app. Now after a new release there is no "debugShowCheckedModeBanner: false," code line in the main .dart file. So I think these methods are effective:

If you are using Visual Studio Code, then install `"Dart DevTools" from extensions. After installation, you can easily find the "Dart DevTools" text icon at the bottom of Visual Studio Code. When you click on that text icon, a link will be opened in Google Chrome. From that link page, you can easily remove the banner by just tapping on the banner icon as shown in this screenshot.

NOTE: Dart DevTools is a Dart language debugger extension in Visual Studio Code

If Dart DevTools is already installed in your Visual Studio Code, then you can directly open Google Chrome and open the URL "127.0.0.1: ZZZZZ/?hide=debugger&port=XXXXX"

Note: In this link, replace "XXXXX" by 5 digit port-id (on which your Flutter app is running) which will vary whenever you use the flutter run command and replace "ZZZZZ" by your global (unchangeable) 5 digit debugger-id

Note: These Dart developer tools are only for the Google Chrome browser

Three ways to remove flutter debug banner:

1. In the MaterialApp/ScaffoldApp

Snippet

MaterialApp(
  debugShowCheckedModeBanner: false,
)

ScaffoldApp(
             debugShowCheckedModeBanner: false,
        );

2.By making release version of your app

For running release version of your app, use this command

flutter run --release

Or if using real devices rather than emulators or simulators. make a build version of the app.

flutter build apk

3.BY using dart dev tool to remove debug banner

IN vs code type ctr+shift+pin windows and for mac cmd+shift+p and use this command to open dart dev tool

Dart: Open DevTools

Solution 6:^[6]

The debug banner appears only while in development and is automatically removed in the release build.

To hide this there is a need to set debugShowCheckedModeBanner to false

MaterialApp(
  debugShowCheckedModeBanner: false,
)

Solution 7:^[7]

On your MaterialApp set debugShowCheckedModeBanner to false.

 MaterialApp(
    debugShowCheckedModeBanner: false,
  )

The debug banner will also automatically be removed on release build.

If you are using emulator or real device and you want to check it on release mode then =>

   flutter run release --apk

run this command on terminal Android Studio / Vs Code

Solution 8:^[8]

Use:

MaterialApp(
  debugShowCheckedModeBanner: false,
)

This is the code for removing this banner. The debug banner is due to MaterialApp, e.g., you can see this banner on all that pages that use MaterialApp.

There should be at least one MaterialApp in your app on main root.

Solution 9:^[9]

All other answers are great for Android Studio, but if using Visual Studio Code there is a command you can use to toggle this easily. Open the command palette (Mac: Cmd + Shift + P or Windows: Ctrl + Shift + P). Then type toggle debug-mode banner as shown below:

Solution 10:^[10]

To remove the Flutter debug banner, there are several possibilities:

The first one is to use the debugShowCheckModeBanner property in your MaterialApp widget.

Code:
```
MaterialApp(
  debugShowCheckedModeBanner: false,
)
```
And then do a hot reload.
The second possibility is to hide debug mode banner in Flutter Inspector if you use Android Studio or IntelliJ IDEA.
The third possibility is to use Dart DevTools.

Solution 11:^[11]

In a Material app set debugShowCheckedModeBanner to false.

Solution 12:^[12]

official example

MaterialApp(
  home: Scaffold(
    appBar: AppBar(
      title: const Text('Home'),
    ),
  ),
  debugShowCheckedModeBanner: false, //setup this property
)

for more information, view the official documentation.

Solution 13:^[13]

Just do this in your MaterialApp or GetMaterialApp add this line debugShowCheckedModeBanner to false.

like this

MaterialApp(
  debugShowCheckedModeBanner: false,
)

Solution 14:^[14]

It's the app.dart class property.

It displays a banner, saying "DEBUG" when running in checked mode. MaterialApp builds one of these by default.

For disabling this banner in debug mode also, you can set a Boolean false.

return MaterialApp(
  theme:....
  debugShowCheckedModeBanner: false,
  home: SplashScreen(),
);

In release mode this has no effect.

Solution 15:^[15]

If you use Scaffold in Return Section so add on Top MaterialApp and Restart

void main() => runApp(
      const MaterialApp(
                 debugShowCheckedModeBanner: false, 
                 home: Home()),
      );

Solution 16:^[16]

Go to main in the Lib folder find MaterialApp() and type debugShowCheckedModeBanner: false,

MaterialApp( debugShowCheckedModeBanner: false, )

Solution 17:^[17]

If you are still in debug mode, you can switch to release mode and the banner will be gone.

You can also open the same Run/Debug Configurations window via shortcuts:

ALT+SHIFT+F10, then Press 0 and Press ALT+a.

Now enter --release.

Solution 18:^[18]

You can use:

debugShowCheckedModeBanner: false,

inside materialapp

Solution 19:^[19]

use this

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: AppTheme.appTheme,
      home: HomePage(),
    );
  }
}
