使用flutter_localizations与intl时出现奇怪的语法错误

• 开发场景：基于Flutter开发支持多语言（英语、法语、阿拉伯语、荷兰语等）的Web及桌面应用，严格遵循官方国际化流程操作。
• 初始状态：可正常在app_en.arb、app_fr.arb等文件中添加对应语言文本，热重载/重启应用时会自动重建本地化Dart文件。
• 当前问题：执行热重载/重启时抛出错误，本地化Dart文件不再自动重建，仅能通过手动执行命令重建。

错误信息 #

Exception: Found syntax errors.

临时解决方式 #

手动执行以下命令重建语言文件：

flutter gen-l10n
