Can you please try the following in pubspec.yaml

  flutter_google_places:
    git:
      url: https://github.com/fluttercommunity/flutter_google_places
      ref: v0.3.2

I am a beginner in both formats but I have not found more information thanks
I have entered my key if you enter a letter it works perfectly but if you don't enter it, an error appears

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following _CastError was thrown while finalizing the widget tree:
Null check operator used on a null value
PlacesAutocompleteState.dispose (package:flutter_google_places/src/flutter_google_places.dart:467:14)

In flutter_google_places.dart main class it add listener in initState()
Timer? _debounce;

@OverRide
void initState() {
super.initState();
_queryTextController!.addListener(_onQueryChange); // added listener
}

in the listener it initialized the _debounce.

void _onQueryChange() {
if (_debounce?.isActive ?? false) _debounce!.cancel();
_debounce = Timer(Duration(milliseconds: widget.debounce), () {
if (!_queryBehavior.isClosed) {
_queryBehavior.add(_queryTextController!.text);
}
});
}
in dispose method it cancels the _debounce with ! operator .
@OverRide
void dispose() {
super.dispose();

_debounce!.cancel();

}

So when we back button pressed without entering text add listener not called and _debounce is not initialized and on dispose we cancel the debounce with ! operator which throws the error because it is not initialized.

So change the _debounce!.cancel() to _debounce?.cancel() will solve the error.

I'm having the same issue, and manually changing _debounce!.cancel() to _debounce?.cancel() worked for me too. Would be great to have this included in a release.
