Flutter - Error: 'xxx' is imported from both 'package:xxx' and 'package:xxx'

Compiler message:
lib/main.dart:77:32: Error: 'Toast' is imported from both
'package:easy_alert/src/provider.dart' and 
'package:fluttertoast/fluttertoast.dart'.
toastLength: Toast.LENGTH_LONG);

由于引用的”Toast”同时存在于package easy_alert 和 fluttertoast中，编译器不确定到底是引用的哪一个包中的Toast，因此报错。

解决方法：

import 'package:easy_alert/easy_alert.dart' as easyAlertV;
import 'package:fluttertoast/fluttertoast.dart' as flutterToastV;

原代码：

Fluttertoast.showToast(msg: "数据存储成功",
                    toastLength: flutterToastV.Toast.LENGTH_SHORT,
                    gravity: flutterToastV.ToastGravity.BOTTOM,
                    timeInSecForIos: 1
                  );

修改后：

flutterToastV.Fluttertoast.showToast(msg: "数据存储成功",
                    toastLength: flutterToastV.Toast.LENGTH_SHORT,
                    gravity: flutterToastV.ToastGravity.BOTTOM,
                    timeInSecForIos: 1
                  );
