Flutter - 谷歌地图在调整大小时崩溃

Question

在我的用例中，我需要确保我的地图可以动态调整大小而不会崩溃，您可能会建议使用 resizeToAvoidBottomPadding，但我的问题不止于此，例如，如果我使用 facebook messanger 聊天头，我的应用程序会崩溃并打开它的键盘（这使应用程序调整大小，迫使地图调整大小，因此崩溃）

以下代码在子路由内（在包含底部标签栏的路由内，因此以下代码在该栏的按钮之一内）

@override
  Widget build(BuildContext context) {
    return Stack(
      children: <Widget>[
        GoogleMap(
          onMapCreated: _onMapCreated,
          mapType: MapType.normal,
          initialCameraPosition: CameraPosition(
            target: LatLng(30, 40),
            zoom: 11,
          ),
          onCameraMove: (pos) {
            setState(() {
              // do something
            });
          },
          onCameraIdle: () {
            setState(() {
              // do something
            });
          },
        ),
        TextField(),
      ],
    );
  }

编辑：这是我在控制台中收到的错误消息：

感谢您的帮助。

Answer 1

这是一个错误related to changes in Gradle 3.5.0。目前已在 Flutter 主频道中修复。

如果您想立即解决此问题，请将 android.enableDexingArtifactTransform=false 添加到您的 gradle.properties 文件以禁用新的 Gradle 更改。

1. 用 Expanded 小部件包装您的 Stack
2. 用列包裹展开的小部件
