how can remove the Flutter debug banner?

This is how you can remove the Flutter debug banner;
solution 1

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

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

  1. If you are using VS Code, then install "Dart DevTools" from extensions. After installation, you can easily find "Dart DevTools" text icon at the bottom of the VS Code. When you click on that text icon, a link will be open 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 VS Code

  1. If Dart DevTools is already installed in your VS Code, then you can directly open the google chrome and open this 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 "flutter run" command and replace “ZZZZZ” by your global(unchangeable) 5 digit debugger-id

NOTE:– these dart dev tools are only for “Google Chrome Browser”

Here are other 3 ways to do it

  • 1 : On your MaterialApp set debugShowCheckedModeBanner to false. MaterialApp( debugShowCheckedModeBanner: false ) The slow banner will also automatically be removed on release build.
  • 2 : If you are using Android Studio, you can find the option in the Flutter Inspector tab –> More Actions.
