image - 即使在pubspec.yaml Flutter中指定了 Assets ，也不会在GridView中显示图像

Question

我现在正在开发一个菜单信息亭应用程序，在将图像加载到我的应用程序时遇到一些问题，我确保在pubspec.yaml中指定了每个图像，但是这些图像仍然没有显示。我得到的错误是这样的: ════════ Exception caught by image resource service ════════════════════════════ Unable to load asset: assets/images/sideDesserts/Dippers with Choco Dip.png ════════════════════════════════════════════════════════════════════════════════
这是我的pubspec.yaml包含的内容

# To add assets to your application, add an assets section, like this:

我还为不同的菜单类型创建了自定义静态列表模型，示例如下:

class BarkadaData {
  String name;
  String imagePath;
  double price;

  BarkadaData({this.imagePath, this.name, this.price});

  static List<BarkadaData> barkadaList = [
    BarkadaData(
        name: 'Barkada Bundle A (for 3)',
        price: 469.00,
        imagePath: 'assets/images/barkada/Barkada Bundle A.png'),
    BarkadaData(
        name: 'Barkada Bundle B (for 4)',
        price: 569.00,
        imagePath: 'assets/images/barkada/Barkada Bundle B.png'),
    BarkadaData(
        name: 'Barkada Bundle C (for 6)',
        price: 969.00,
        imagePath: 'assets/images/barkada/Barkada Bundle C.png'),
  ];
}

最后，我使用GridView.builder显示它，我的小部件树如下所示:

                      Container(
                        width: MediaQuery.of(context).size.width * .75,
                        child: GridView.builder(
                          itemCount: barkadaList.length,
                          gridDelegate:
                              SliverGridDelegateWithFixedCrossAxisCount(
                                  crossAxisCount: 3),
                          itemBuilder: (BuildContext context, int index) {
                            return InkWell(
                              onTap: () {
                                print(barkadaList[index].name);
                              },
                              child: Padding(
                                padding: const EdgeInsets.all(8.0),
                                child: Stack(
                                  children: <Widget>[
                                    Container(
                                      width: MediaQuery.of(context).size.width *
                                          .22,
                                      child: Image(
                                        image: AssetImage(
                                            barkadaList[index].imagePath),
                                      ),
                                    ),
                                    Text(
                                      '${barkadaList[index].name}',
                                      style: TextStyle(
                                          fontWeight: FontWeight.w600,
                                          fontSize: 18),
                                      textAlign: TextAlign.center,
                                    )
                                  ],
                                ),
                              ),
                            );
                          },
                        ),
                      )

如您所见，gridview.builder之所以有效，是因为名称正在显示，只有图像没有显示。任何帮助，将不胜感激

Answer 1

重命名您的图片。您的图片名称有空格。在android图像中无法使用空间名称加载。因此，使用Choco Dip 将您的图像名称 Dippers重构为 Dippers_with_Choco_Dip
