Is your feature request related to a problem? Please describe.
When users navigate to another screen while being in Feedback mode, we lose the context and thus can not use any function that uses the context.

BetterFeedback.of(context).show((feedback) async {
if (feedback.text.isNotEmpty) {
if (context.mounted){
await ref.read(uploadFeedbackProvider(
feedback: feedback.text, screenshot: feedback.screenshot).future. // this will not be executed if user navigate during feedback mode. if we remove context.mounted then app will throw error.
);}
EasyLoading.showSuccess('Thanks for the feedback!');
}
});

Describe the solution you'd like
allow option to disable navigation during feedback widget is open
