flutter - 在 Flutter 中意外删除了 dart 包

Question

我不小心删除了 flutter_material_color_picker-1.1.0+2 包文件夹，它是 flutter-settings-screens 的一部分。现在，当我尝试运行该应用程序时，出现此错误：

../../MobileDev/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_settings_screens-0.2.2+1/lib/src/widgets/settings_widgets.dart:3:8：错误：读取时出错'../../MobileDev/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_material_color_picker-1.1.0+2/lib/flutter_material_color_picker.dart'：没有这样的文件或目录导入'package:flutter_material_color_picker/ flutter_material_color_picker.dart';

我试过了：

删除 pubspec.lock

扑干净
