解决建议 #

• 检查导入语句是否正确：wakelock_plus的正确导入路径是import 'package:wakelock_plus/wakelock_plus.dart';，确认拼写无错误。
• 重启IDE：IDE缓存可能导致依赖识别延迟，关闭并重新打开项目所在IDE（如Android Studio/VS Code）。
• 清除Flutter缓存：执行flutter clean后重新运行flutter pub get。
• 重新生成依赖锁文件：删除pubspec.lock文件，再执行flutter pub get让Flutter重新生成完整依赖记录。
• 重置IDE缓存：VS Code可执行"Restart Dart Analysis Server"；Android Studio点击"File -> Invalidate Caches..."后重启IDE。
• 验证SDK兼容性：尝试升级Flutter到稳定版最新版本，确保与wakelock_plus 1.2.4版本兼容。
