Flutter intl版本冲突引发awesome_notifications构建失败及Java编译错误求助

我现在遇到了一个棘手的Flutter包版本冲突问题，折腾了好一阵都没找到干净的解决办法，来求助大家！

问题背景 #

我的项目里几个依赖的intl版本要求互相冲突，具体情况是：

• flutter_localizations 依赖 intl: 0.19.0
• 我原本项目里用的是 intl: ^0.20.0
• awesome_notifications: ^0.10.1 同样依赖 intl: ^0.20.0

为了适配flutter_localizations，我把intl降级到了0.19.0，结果awesome_notifications新版本不兼容这个intl版本，只能跟着降级到0.10.0。但降级后，构建时又出现了Java编译错误：

DartBackgroundExecutor.java:74: error: cannot find symbol
private static io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback ^
symbol: class PluginRegistrantCallback
location: interface PluginRegistry
DartBackgroundExecutor.java:86: error: cannot find symbol
io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback callback) { ^
symbol: class PluginRegistrantCallback
location: interface PluginRegistry

当前困境 #

现在我陷入了两难：

• 用intl 0.19.0：flutter_localizations正常，但awesome_notifications 0.10.0出现上述Java编译错误
• 用intl 0.20.0：awesome_notifications正常，但flutter_localizations版本冲突

我需要的帮助 #

我希望能找到以下两种解决方案之一：

1. 让flutter_localizations、intl、awesome_notifications三者能兼容共存的方法
2. 解决awesome_notifications 0.10.0中PluginRegistrantCallback找不到的问题的临时/workaround方案

最好是不用手动fork修改包的干净解决办法，真的太感谢大家了！
