When developing Flutter applications, you may notice a debug banner displaying in the top right corner of your app. This banner is intended for development purposes, indicating that the app is running in debug mode. However, during development or when taking screenshots, you might want to remove this banner for a cleaner presentation.
Solution: Disable the Debug Banner
The most straightforward method to remove the debug banner in Flutter is by setting the debugShowCheckedModeBanner property to false in your MaterialApp widget. This property controls whether the banner should be displayed, and setting it to false will hide the banner.
Implementation Steps
-
Open your main Dart file where the
MaterialAppis defined. -
Locate the
MaterialAppwidget and set thedebugShowCheckedModeBannerproperty tofalseas shown below:MaterialApp( debugShowCheckedModeBanner: false, ) - Save the file and perform a hot reload to apply the changes.
Additional Methods
If you are using an Integrated Development Environment (IDE) like Android Studio or Visual Studio Code, you can also manage the debug banner through the IDE’s Flutter Inspector or Dart DevTools. However, these methods may vary based on the tools and versions used, and the primary solution remains the most consistent across various environments.
Running in Release Mode
Another approach to ensure the debug banner is not displayed is to run your app in release mode. This mode is optimized for end-user deployment and automatically suppresses the debug banner:
flutter run --release
