AutomaticKeepAliveClientMixin for GetView?

[phamquoctrongdev]

I tried with AutomaticKeepAliveClientMixin but get an error.

AutomaticKeepAliveClientMixin<StatefulWidget>' can't be mixed onto 'GetView<MyController>' because 'GetView<MyController>' doesn't implement 'State<StatefulWidget>'.

What replace it? Thanks...

GetView is a StatelessWidget and AutomaticKeepAliveClientMixin can be used only with StatefulWidget

I will reopen and move to discussions, because I think about implement this resource on future

/// Page - StatefulWidget
class TestPage extends StatefulWidget {
  TestPage({Key? key}) : super(key: key);

  @override
  _TestPageState createState() => _TestPageState();
}

/// Page - State with AutomaticKeepAliveClientMixin
class _TestPageState extends State<TestPage>
    with AutomaticKeepAliveClientMixin {
  @override
  Widget build(BuildContext context) {
    return TestView();
  }

  @override
  bool get wantKeepAlive => true;
}

/// GetView
class TestView extends GetView<TestController> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(body: Text('TestPage'));
  }
}

/// Controller
class TestController extends GetxController {

}

Try this

import 'package:flutter/material.dart';
import 'package:get/get.dart';

abstract class GetViewKeepAlive<T> extends StatefulWidget {
  const GetViewKeepAlive({super.key, this.tag});

  @override
  State<GetViewKeepAlive<T>> createState() => _GetViewKeepAliveState<T>();

  @protected
  Widget build(BuildContext context);

  @protected
  final String? tag;

  @protected
  T get controller => GetInstance().find<T>(tag: tag)!;
}

class _GetViewKeepAliveState<T> extends State<GetViewKeepAlive<T>> with AutomaticKeepAliveClientMixin {
  @override
  Widget build(BuildContext context) {
    super.build(context);
    return widget.build(context);
  }

  @override
  bool get wantKeepAlive => true;
}

Change your existed view from
class RickRollView extends GetView<RickRollController>
to
class RickRollView extends GetViewKeepAlive<RickRollController>
