How to solve "Do not use BuildContext across async gaps" in Riverpod's ConsumerWidget? – Flutter

I get the warning "Do not use BuildContext across async gaps" when I use code like this:

await ref.read(testFutureProvider.notifier).doSomethingAsync();
Navigator.of(context).pop();

Normally it is possible to check the mounted property like this:

if(!mounted) return;

or

if(!context.mounted) return;

How can I avoid using BuildContext across async gaps in Riverpod in a ConsumerWidget?

    The solution is to retrieve everything depending on your BuildContext before running async code:

    NavigatorState nav = Navigator.of(context);
await ref.read(testFutureProvider.notifier).doSomethingAsync();
nav.pop();

    Try this:

    ref.read(testFutureProvider.notifier).doSomethingAsync().then((value){
    Navigator.of(context).pop();
})

    Try the following code:

    try {
  await ref.read(testFutureProvider.notifier).doSomethingAsync();
} catch (e) {
  debugPrint(e);
} finally {
  Navigator.of(context).pop();
}

    await ref.read(testFutureProvider.notifier).doSomethingAsync().then((value) => Navigator.of(context).pop()).catchError((e) => debugPrint(e));

    I suggest you choose one of the two codes above as they both check for errors for you.
