Flutter 1.12.13+hotfix.5 • channel stable • https://github.com/flutter/flutter.git

Tools • Dart 2.7.0

我今天将 Flutter 更新到最新版本，并收到此错误并阅读了 repo readme并采取行动。感谢包所有者 Rene Floor 现在一切正常

只需在 pubspec.yaml 中增加包按照楼主的建议:

cached_network_image: ^2.0.0-rc

由包所有者:

Breaking change with ImageProvider.load in Flutter 1.10

The Flutter team made a breaking change with the ImageProvider in Flutter 1.10.15 (currently Master channel only).

If you are experiencing one of the following errors upgrade to 2.0.0-rc.

The method 'ScaledFileImage.load' has fewer positional arguments than those of overridden method 'ImageProvider.load'
