I have this project which works fine when I had not added [chatview: ^1.2.0+1][1]. Now after adding it as a dependency, I get an error of

Because chatview >=1.0.0 depends on intl ^0.18.0 and mobile_app depends on intl ^0.17.0, chatview >=1.0.0 is forbidden. So, because mobile_app depends on chatview ^1.2.0+1, version solving failed. pub get failed command: "/Users/samuel/flutter/bin/cache/dart-sdk/bin/dart __deprecated_pub --directory . get --example" pub env: { "FLUTTER_ROOT": "/Users/samuel/flutter", "PUB_ENVIRONMENT": "vscode.dart-code:flutter_cli:get", "PUB_CACHE": "/Users/samuel/.pub-cache", } exit code: 1

Now i changed the version of my intl package to intl ^0.18.0 which I expected to work fine but I also got another error of

Because mobile_app depends on flutter_localizations from sdk which depends on intl 0.17.0, intl 0.17.0 is required.

Now I don't know what to do again. Below is my pubspec.yaml file

**得分**: 14

最近有一个更新，扩大了Flutter SDK本地化的依赖版本，要求>=0.17.0但<0.19.0。

所以我只是覆盖了我的依赖以使用0.18.0：
```yaml
dependency_overrides:
  intl: ^0.18.0

dependency_overrides:
  intl: ^0.18.0

问题在于flutter_localizations目前依赖于intl 0.17.0。所以您现在唯一的选择是将chatview降级到使用intl 0.17.0的版本。

看起来flutter_localizations正在更新以使用intl 0.18.0，但这个更新还没有进入稳定的Flutter渠道。
详情请参见：https://github.com/flutter/flutter/issues/117163

覆盖 pubspec.yaml 文件中的依赖项，按照以下方式进行：

dependency_overrides:
  intl: ^0.18.0
