Dart/Flutter 命名冲突，导致import重复，变异失败，Compiler message: is imported from both

Log:

Compiler message:
lib/page.dart:92:11: Error: 'showDialog' is imported from both 'package:flutter/src/material/dialog.dart' and 'package:loading/loading.dart'.
          showDialog<void>(
          ^^^^^^^^^^

重复导入，导致变异失败。

两种解决方案：

1.使用hide，把其中一个improt 使用hide隐藏掉冲突名字

import 'package:loading/loading.dart' hide showDialog;

2.使用as,重命名

import 'package:loading/loading.dart' as showMyDialog;
