如何仅禁用现有文件的Lint规则，保留Dart Analyzer代码提示？

核心问题是你用了analyzer.exclude，这个配置会让Dart Analyzer完全跳过指定文件的所有分析工作——包括Lint检查、类型校验、智能提示等。要实现只禁用Lint规则、保留其他分析功能，得用针对性的排除配置，而不是直接排除整个文件的Analyzer处理。

具体修改步骤： #

1. 清理analyzer.exclude配置
   把你业务代码相关的文件从analyzer.exclude中移除，只保留真正不需要Analyzer处理的文件（比如测试文件、自动生成的代码可根据情况保留）。这样Analyzer会继续处理这些文件，智能提示和类型校验就能正常工作。

2. 给官方Lint规则添加文件排除
   在linter节点下新增exclude字段，把现有业务文件加进去。这个配置只会让官方Lint规则跳过这些文件，不影响Analyzer的其他功能。

3. 给dart_code_metrics规则添加文件排除
   在dart_code_metrics节点下新增rules-exclude字段，同样把现有业务文件加进去，禁用它的自定义规则检查，但保留metrics分析（如果不需要metrics也可调整metrics-exclude）。

效果说明 #

修改后：

• 现有业务文件不会触发你配置的任何Lint规则（官方+dart_code_metrics）
• Analyzer仍然会处理这些文件，智能提示、类型检查、代码建议等功能完全正常
• 新创建的文件会自动应用所有Lint规则，无需额外配置
