Flutter toast库配置,可参考fluttertoast配置引用
1.在pubspec.yaml中配置fluttertoast库，通过Pub get 获取fluttertoast的版本，通过Pub upgrade更新，eg:
|

# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons
class
for
iOS style icons.
cupertino_icons: ^1.0.2
provider: ^5.0.0
fluttertoast: ^8.0.8 |
2.在需要显示toast的dart文件中，import fluttertoast.dart,eg:
|
1 |
import
'package:fluttertoast/fluttertoast.dart'
; |
