解决方法 #

• 调整platform包版本：platform 3.1.4要求的Dart版本高于当前的2.19，在dependency_overrides中将platform版本改为兼容Dart 2.19的3.0.0：

  dependency_overrides:
    platform: 3.0.0
  

• 统一Firebase包版本：当前Firebase各包版本存在接口不匹配，需确保所有Firebase相关包版本兼容Flutter 3.7.0和Dart 2.19，推荐使用以下版本组合（替换原有的Firebase相关override）：

  dependency_overrides:
    firebase_core: ^2.4.0
    firebase_core_web: ^2.0.1
    firebase_messaging: ^14.1.0
    firebase_messaging_web: ^3.1.10
    firebase_storage: ^11.0.9
    firebase_core_platform_interface: ^4.1.0
    firebase_messaging_platform_interface: ^4.1.6
  

  若不需要强制覆盖，可直接移除Firebase相关的dependency_overrides，让pub自动解析兼容版本。
• 清理缓存并重新拉取依赖：执行以下命令清除旧缓存并获取匹配的依赖：

  flutter clean
  flutter pub get
  

• 检查其他依赖兼容性：确认abg_utils、html_editor_enhanced等第三方包是否支持Flutter 3.7.0和Dart 2.19，若存在不兼容，降级到对应版本。
