当我尝试在手机中运行我的 flutter 代码时，它显示此错误：
Error: 'DecoderCallback' isn't a type.
ImageStreamCompleter load(AdvancedNetworkImage key, DecoderCallback decode) {
这是我的 pubspec.yaml 文件：

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: "none" # Remove this line if you wish to publish to pub.dev
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
- family: Recoleta Alt
fonts:
- asset: fonts/Recoleta Alt.ttf
weight: 400
- family: AbhayaLibre-ExtraBold
fonts:
- asset: fonts/AbhayaLibre-ExtraBold.ttf
weight: 800
- family: NotoEmoji
fonts:
- asset: fonts/NotoColorEmoji-Regular.ttf
weight: 400

显示依赖项“flutter_advanced_networkimage_2：^2.0.1”的错误 我尝试检查它是否与颤振兼容，但没问题。 我尝试将依赖项更新为较新的依赖项，但它表明很少有依赖项不兼容。 我尝试将频道从主频道更改为稳定频道，但这也不起作用。
我也有同样的错误。
您可以简单地升级依赖项，如下所示：
