======== Exception caught by image resource service ================================================
The following assertion was thrown resolving an image codec:
Unable to load asset: assets/images/888.png

When the exception was thrown, this was the stack:
#0 PlatformAssetBundle.load (package:flutter/src/services/asset_bundle.dart:237:7)

#1 AssetBundleImageProvider._loadAsync (package:flutter/src/painting/image_provider.dart:658:14)

Image provider: AssetImage(bundle: null, name: “assets/images/888.png”)
Image key: AssetBundleImageKey(bundle: PlatformAssetBundle#05eaa(), name: “assets/images/888.png”, scale: 1.0)

错误的写法

flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true
  # To add assets to your application, add an assets section, like this:
assets:
     - assets/images/

正确的写法

# The following section is specific to Flutter packages.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true
  # To add assets to your application, add an assets section, like this:
  assets:
     - assets/images/

即 assets 和 uses-material-design: true 是对齐的
