如何在等待Future.wait的同时旋转摄像头的轴承，并在Flutter谷歌地图中完成后停止它

import 'package:flutter/material.dart';

class CameraRotationWidget extends StatefulWidget {
  @override
  _CameraRotationWidgetState createState() => _CameraRotationWidgetState();
}

class _CameraRotationWidgetState extends State<CameraRotationWidget>
    with SingleTickerProviderStateMixin {
  AnimationController _controller;
  GoogleMapController _mapController;

  @override
  void initState() {
    super.initState();
    _controller = AnimationController(
      duration: const Duration(seconds: 5),
      vsync: this,
    )..repeat();
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  Future<void> _waitForFuture() async {
    // 等待Future的完成
    await Future.wait([
      // 在这里添加需要等待的Future
      Future.delayed(Duration(seconds: 3)),
      Future.delayed(Duration(seconds: 5)),
    ]);

    // 停止摄像头轴承的旋转
    _controller.stop();
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        // 谷歌地图
        Expanded(
          child: GoogleMap(
            onMapCreated: (controller) {
              _mapController = controller;
            },
          ),
        ),
        // 旋转摄像头的轴承
        RotationTransition(
          turns: _controller,
          child: Icon(Icons.camera),
        ),
        // 按钮，点击后开始等待Future并旋转摄像头轴承
        RaisedButton(
          onPressed: () {
            _waitForFuture();
            _controller.repeat();
          },
          child: Text('开始等待Future并旋转摄像头轴承'),
        ),
      ],
    );
  }
}
