flutter地图框地图显示/布局问题在Android上

Question

我是Flutter的新手，并试图将MAPBOX MAP与iOS和Android应用中的转弯导航进行集成。

我正在使用 flutter_mapbox_navigation 软件包和 mapboxNavigationView 。

• ios：按预期工作

• Android API 30：Mapbox徽标似乎表明窗口小部件在正确的位置，但是在正确的位置，但是地图本身不在

• Android API 27、28和29：地图似乎显示正确，但是Mapbox徽标不可见，对我来说，这仍然表明某物仍然关闭

• android api 26：MAP和MAPBOX徽标在正确位置可见

• Android API 24和25：Mapbox logo在正确的位置，但MAP在MAP上不可见。全部

我尝试了不同的方法来尺寸和定位窗口，但问题仍然存在。

我尝试使用Flutter小部件检查员，但据我所知，一切似乎都不错。 我尝试使用Android Studio布局，但看到了一个空白页。

我已经找到了这个线程，但是没有解决方案 mapbox Map在Android上未显示

Main.dart

import 'package:flutter/material.dart';
import 'package:flutter_mapbox_navigation/library.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  MyApp({Key? key}) : super(key: key);

  final _options = MapBoxOptions();
  Future<void> _onRouteEvent(e) async {}

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Column(
        children: [
          const Text("test"),
          Center(
            child: SizedBox(

找到了解决方案。

我删除了 flutter_mapbox_navigation 包装和使用Platform> Platform> Platform> PlatformView。起初我仍然遇到同样的问题，但是后来我发现了textureView选项，这解决了我的问题。

val resourceOptions = ResourceOptions.Builder()
            .accessToken(context.getString(R.string.mapbox_access_token))
            .build()

mapView = MapView(context, MapInitOptions(context, resourceOptions).apply { textureView = true })
