flutter - 断言失败 : line 24 pos 15: 'initialCameraPosition != null' : is not true

Question

我在 pubspec.yaml 中插入了下面的库

  google_maps_flutter:
    git:
      url: git://github.com/flutter/plugins
      path: packages/google_maps_flutter

但是每次都报错

另一个异常被抛出:'file:///C:/src/flutter/.pub-cache/git/plugins-aedcc6f81843ae2da3a6ac0c8e8c4b530d1ac035/packages/google_maps_flutter/lib/src/google_map.dart':断言失败: line 24 pos 15: 'initialCameraPosition != null': is not true.

提前致谢。

只需在 GoogleMap() 中使用 initialCameraPosition例如:

GoogleMap(
              onMapCreated: _onMapCreated,
              initialCameraPosition: CameraPosition(target: LatLng(51.5160895, -0.1294527),),
            )
