URI的目标不是exist:package:gradient_input_border/gradient_input_border.dart

Question

我是刚从android背景中跳出来的，我在VS和Android中都导入了一个but项目，但是我在这些导入语句上得到了Target URI dosen不费的钱。

import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:gradient_input_border/gradient_input_border.dart';

我的pubsec.yaml文件在下面。

我已经尝试过的东西

• 命令 颤振清洁颤振酒吧获得颤振包升级
• 使Android上的缓存/重新启动无效
• 重新启动Visual。

您需要安装套餐。

dependencies:

   // Add this dependency under dependecies as shown.
   gradient_input_border: ^1.0.0

然后运行flutter pub get。

编辑1:对flutter_localizations试一试，

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter
