dart - 错误 : The name 'Image' is defined in the libraries 'package:flutter/src/widgets/image.dart' and 'package:image/src/image.dart' . -- ambiguous_import

Question

如何解决 Dart 中的这种歧义错误。

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:camera/camera.dart';
import 'package:image/image.dart';

return MaterialApp(
  title: 'Camera',
  home: Scaffold(
    body: new Container(
      child: _image == null ? Text('No Image to display') : Image.file(_image),
    ),
    floatingActionButton: new FloatingActionButton(onPressed:() {
      picker();
    },
    tooltip: 'Pick image',
    child: new Icon(Icons.camera)),
  ),
);

错误:

The name 'Image' is defined in the libraries 'package:flutter/src/widgets/image.dart' and 'package:image/src/image.dart'. (ambiguous_import at [camera] lib\packs\reg.certificate.dart:45)

Image 在 Flutter Widget 库 中定义，也在 'package:image/image.dart' 中定义。但是我想从 Flutter Widget library 中引用它怎么做？

这是 package:image/image.dart--> 用于解码图像的库的图像。

Answer 1

如果您有一个名为 import 的文件，例如:

Import ‘package:image/image.dart’ as Image;

那么该包中的类将是Image.image。
