Answer 1

On your MaterialApp set debugShowCheckedModeBanner to false.

MaterialApp(
  debugShowCheckedModeBanner: false,
)

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

Usage: return new MaterialApp( home: new LoginPage(), debugShowCheckedModeBanner: false, theme: new ThemeData( primarySwatch: Colors.green, )); – Strand

do i need to use debugShowCheckedModeBanner: false on each class means activity ? – Ariminum

The flutter tool's built-in screenshot command also knows how to automatically remove the "debug" banner while taking a screenshot if that's helpful. – Someone

@EricSeidel Not by default it doesn't (Flutter 1.16.4-pre.18 • channel master • github.com/flutter/flutter.git Framework • revision c8efcb632b (6 weeks ago) • 2020-03-27 22:31:01 -0700 Engine • revision 3ee9e3d378) Is there a trick to enable this? – Coolant

Is there any way to show it in release build? I am building a release versions but for dev/production environments – Chiseler

ehmmm guys it's been outdated but I need to ask. what if I don't have a MaterialApp widget in my project? where should I put the debugshowcheck property? or maybe is there another way around getting rid of that debug text? – Caterer

@AlexAngelico no need of new keyboard – Zincograph

@Caterer If you are using WidgetsApp, MaterialApp, or CupertinoApp, the process is the same. Otherwise, there should be no debug banner by default. If you wish to have the banner, wrap your tree with a CheckedModeBanner widget. – Bathy

@Moti Bartov Just show your own little picture? – Observance

• 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.

Answer 3

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.

Answer 4

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":

Answer 5

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,
)

Three ways to remove flutter debug banner:-

1. In the MaterialApp/ScaffoldApp

Snippet

MaterialApp(
  debugShowCheckedModeBanner: false,
)

OR

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

Answer 7

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:

1. 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

2. 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

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

Answer 9

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

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

   Code:

   MaterialApp(
     debugShowCheckedModeBanner: false,
   )
   

   And then do a hot reload.

2. The second possibility is to hide debug mode banner in Flutter Inspector if you use Android Studio or IntelliJ IDEA.

3. The third possibility is to use Dart DevTools.

Answer 10

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.

Answer 11

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:

Bergeron

Answer 12

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.

Answer 13

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.

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

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

Matronage

Answer 15

This is the simplest way.

For : MaterialApp( debugShowCheckedModeBanner: false )

For : CupertinoApp( debugShowCheckedModeBanner: false )

If you are logically handle another flutter components them you use a bool variable & handle it. For Example bool isDebug === false ;

if(isDebug == true) { debugShowCheckedModeBanner: true }

else { debugShowCheckedModeBanner: false }
