Answer 1

潜在的问题是fluttertoastplugin.java中的android.support.v4.Content.ContextCompat导入无法解析符号ContextCompat。这是一个依赖性问题。

解决方案是转到flutter项目的pubspec.yaml，找到fluttertoast依赖项并将其更新到最新版本（当前为^ 3.1.0）

dependencies:
  flutter:
  sdk: flutter
  dropdown_formfield: ^0.1.0
  camera: ^0.5.2+1
  fluttertoast: ^3.1.0 <----- THIS ONE
  path_provider: ^1.1.0
  video_player: ^0.10.1
  latlong: ^0.6.1
  google_maps_flutter: ^0.5.11+1
  http: ^0.12.0
  flutter_blue: ^0.5.0
  flutter_bluetooth_serial: ^0.0.5
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

就我而言，我所做的只是奔跑了

flutter clean

并重新运行项目，一切正常。

就我而言。我更新了pubspec.yaml中的所有依赖项，并且有效。
