If diffrent snackBar is shown, DoubleBackToCloseApp.snackBar is not shown instantly.

So, I want to add Scaffold.of(context).hideCurrentSnackBar() in _handleWillPop Function.

Hey,

I get this issue with flutter beta

double_back_to_close_app.dart:91:30: Error: No named parameter with the name 'nullOk'. if (Scaffold.of(context, nullOk: true) == null) {

My code: My screen:

When I write the code: content: Text ("Press back again to exit",), that works. How do you use this in your application locales?

Hello, thank you for your plugin

I am trying to make a function to exit app when double tab the back button in the CupertinoTabbar.

However, whenever I tap the back button, an exit message appeared.

Hence I want to build a code work like following:

• just tap back button once, return before pages
• tap twice in few seconds, exit app.

Is it possible to solve these problems using this plugin?

I have also asked in the stackoverflow. Address of it is that:

Thank you!

I am getting this error when a try installing the latest this package as described here.

Because myapp depends on double_back_to_close_app >=1.3.0-nullsafety.1 which requires SDK version >=2.12.0-0 <3.0.0, version solving failed. pub get failed (1; Because myapp depends on double_back_to_close_app >=1.3.0-nullsafety.1 which requires SDK version >=2.12.0-0 <3.0.0, version solving failed.) exit code 1

I have already upgraded to the latest version of the flutter SDK.

I am pushing routes with Navigator to navigate between screens. I have written the package code in my third route. When I double back button press on the third route, it only takes me to my second route. It only works on the first route.

Am I doing something wrong?

The app closes if the user taps the back-button, dismisses the snack bar and quickly taps the back-button again.

This is happening because DoubleBackToCloseAppState.isSnackBarVisible considers the last time the back-button was tapped, not the actual snack bar's visibility.

This behavior is arguably correct, though. However, I think this is not what the user expects, so I'm opening this issue.

Hey,

I'm using a CupertinoTabScaffold with 4 tabs and I've been trying to get this functionality to work with that. Any idea on how to support this feature? The problem I'm having is that the snackbar message is shown on all of the tabs that I have and the users can't exit the app because of that.

So when I double press back, it just pops the page and directs to previous one.

return Scaffold(
      appBar: const HomeAppBar(),
      bottomNavigationBar: const HomeNavigation(selectedIndex: 0,),
      body: DoubleBackToCloseApp(
        snackBar: const SnackBar(
          content: Text('Tap back again to leave'),
        ),
        child: SmartRefresher(
          enablePullDown: true,
          enablePullUp: true,
          child: _feedViews(),
          controller: _refreshController,
          onLoading: () => onLoading(formBloc, _refreshController),
          onRefresh: () => onRefresh(formBloc, _refreshController),
        ),
      ),
    );

Hey, I tried using this package in my where I have already defined a function that displays a snack bar when called. That snack bar is working fine but your package is not doing anything. Rather the app is working the same it was working without your package.
