Flutter 容器中的图像不'；我不想在屏幕上显示飞镖

图像没有显示在我的屏幕上。还有谁能告诉我扁平按钮是怎么回事，矩形也不显示

它应该是这样的：

这是我的屏幕

我的代码：

import 'package:flutter/material.dart';

void main() {
  runApp(

    MaterialApp(
        home: Scaffold(
            backgroundColor: Colors.pink,
            body: Center(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center, children: [
                  new Container(
                  width: 100,
                  height: 100,
                  decoration: new BoxDecoration(
                    shape: BoxShape.circle,
                    image: new DecorationImage(
                      image: new AssetImage("Image/Animegirl.jpg"),
                      fit: BoxFit.fill,
                    ),
                  ),
                ),
                     Text(
                  "Alice Payne",
                  style: TextStyle(fontSize: 50, color: Colors.white),
                 ),
                         Text(
                  "MOBILE DEVELOPER",
                  style: TextStyle(fontSize: 40, color: Colors.white),
                 ),
                        FlatButton.icon(
                          shape: new RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0)),
                            color: Colors.white,
                               label: Text("+212612174968",
                                 style:TextStyle(
                                 color: Colors.grey,
                                   ),
                 ),
                                 icon: Icon(Icons.phone,
                                   size: 25,
                                   color: Colors.white,
                  ),
                               onPressed: (null)
                  ),
                         FlatButton.icon(
                             shape: new RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0)),
                            color: Colors.white,
                            label: Text("hda.karima@gmail.com",
                               style:TextStyle(
                              color:Colors.grey,
                            ),
            ),
                                 icon: Icon(Icons.email,
                                   size: 25,
                                   color: Colors.white,
            ),
                            onPressed: (null)
        ),
        ]),
  ),),


  ),

  );
}

---

还包括

资产

 image: AssetImage("assets/Image/Animegirl.jpg"),

将按下时的

替换为：（空）

onPressed: () {

    }

您看到的样式是禁用的按钮，因为您没有提供onTap方法

还可以根据文件夹结构在pubsub.yaml中添加资产文件夹（如果图像文件夹位于资产文件夹中），并根据文件夹结构进行添加

  assets:
    - assets/Image/
    - assets/

然后使用

image:newassetimage（“assets/image/Animegirl.jpg”）

您的代码应该类似于

import 'package:flutter/material.dart';

void main() {
  runApp(

    MaterialApp(
        home: Scaffold(
            backgroundColor: Colors.pink,
            body: Center(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center, children: [
                  new Container(
                  width: 100,
                  height: 100,
                  decoration: new BoxDecoration(
                    shape: BoxShape.circle,
                    image: new DecorationImage(
                      image: new AssetImage("Image/Animegirl.jpg"),
                      fit: BoxFit.fill,
                    ),
                  ),
                ),
                     Text(
                  "Alice Payne",
                  style: TextStyle(fontSize: 50, color: Colors.white),
                 ),
                         Text(
                  "MOBILE DEVELOPER",
                  style: TextStyle(fontSize: 40, color: Colors.white),
                 ),
                        FlatButton.icon(
                          shape: new RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0)),
                            color: Colors.white,
                               label: Text("+212612174968",
                                 style:TextStyle(
                                 color: Colors.grey,
                                   ),
                 ),
                                 icon: Icon(Icons.phone,
                                   size: 25,
                                   color: Colors.white,
                  ),
                               onPressed: () {

                               }
                  ),
                         FlatButton.icon(
                             shape: new RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0)),
                            color: Colors.white,
                            label: Text("hda.karima@gmail.com",
                               style:TextStyle(
                              color:Colors.grey,
                            ),
            ),
                                 icon: Icon(Icons.email,
                                   size: 25,
                                   color: Colors.white,
            ),
                            onPressed: () {

                               }
        ),
        ]),
  ),),


  ),

  );
}

您是否在pubspec.yaml中添加了“Image/Animegirl.jpg”？
