Implementing Navigator.popToFirst #15493
Description
I have a question about navigation. On instagram in iOS, however you go deep in a tab, when you click the tab you will have one pop action back to your main screen for that tab. I tried popUntil but it shows continues pops.
I implemented a function that does what I want. Before submitting it as a PR to flutter, I want to check if there is another solution for this. And here's the function I created:
/// In flutter/lib/src/widgets/navigator.dart
/// Calls [pop] to `position` after removing all routes between the position and the last.
void popToFirst(int position) {
assert(_history.isNotEmpty);
if (_history.length > position) {
final List<Route<dynamic>> routes =
_history.sublist(position, _history.length - 1);
routes.forEach(removeRoute);
pop();
}
}
