添加Pushe插件时找不到符号@NonNull

标签: flutter flutter-dependencies pushe

我想安装Pushe plugin来防止抖动,但是出现此错误:

我什至将此行添加到本机导入中:

import android.support.annotation.NonNull;

但会遇到相同的异常。

我该怎么解决这个问题?

这是我的堆栈跟踪:

根据 Pushe's Github repo ,此问题已从version 1.0.1开始修复。

  

https://github.com/pusheco/pushe-flutter/releases

Version 1.0.0或更低版本与AndroidX工件不完全兼容,因为Flutter不会触摸插件的代码,也不会迁移它们。
