# The following line prevents the package from being accidentally published to
# pub.dev using `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 information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
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
generate: true
# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# 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: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
this is what I have tried:这是我尝试过的:
flutter clean
运行命令flutter clean
flutter packages get
运行flutter packages get
flutter packages upgrade
运行flutter packages upgrade
flutter pub cache repair
but still not work, what is the reason and what should I do to make it work?但仍然无法正常工作,原因是什么,我该怎么做才能使其正常工作? this is the env info:这是环境信息:

I rename the ~/.pub-cache/hosted/
mirrir name, now I could successful compile in command line, but when I compile using android studio, shows like this :我重命名了~/.pub-cache/hosted/
镜像名称,现在我可以在命令行中成功编译,但是当我使用 android studio 编译时,显示如下:
what should I do to add cache path into my project?我应该怎么做才能将缓存路径添加到我的项目中?
you have你有
import 'package:flutter_riverpod/flutter_riverpod.dart';导入'包:flutter_riverpod/flutter_riverpod.dart'; import 'package:hooks_riverpod/hooks_riverpod.dart';导入'包:hooks_riverpod/hooks_riverpod.dart';
If you are using hooks, use hooks_riverpod, if not, use flutter_riverpod.如果使用 hooks,请使用 hooks_riverpod,如果没有,请使用 flutter_riverpod。 I don't see a reason why you should be using both of them.我不明白为什么你应该同时使用它们。
Also, the error makes sense, because you don't have flutter_riverpod in package.yaml此外,该错误是有道理的,因为 package.yaml 中没有 flutter_riverpod
