use_nearest_context

A rule which checks that we use BuildContext from the nearest available scope.

Example:

BAD:

class SomeWidget extends StatefulWidget {
...
}

class _SomeWidgetState extends State<SomeWidget> {
  ...
  void _showDialog() {
    showModalBottomSheet(
      context: context,
      builder: (BuildContext _) {
        final someProvider = context.watch<SomeProvider>(); // LINT, BuildContext is used not from the nearest available scope

        return const SizedBox.shrink();
      },
    );
  }
}

GOOD:

class SomeWidget extends StatefulWidget {
...
}

class _SomeWidgetState extends State<SomeWidget> {
  ...
  void _showDialog() {
    showModalBottomSheet(
      context: context,
      builder: (BuildContext context)
        final someProvider = context.watch<SomeProvider>(); // OK

        return const SizedBox.shrink();
      },
    );
  }
}
