Flutter接收原生Activity的数据 在Android原生层面(在我们的Activity中)处理分享的文本数据,然后Flutter再通过使用MethodChannel获取这个数据。 Android端Activity:configureFlutterEngine里通过 call 在方法名getSharedText里处理分享的数据,再通过result回掉给最终结果 class MainActivity : FlutterActivity() { companion object ...

这是笔者作为一个Android工程师入门Flutter的学习笔记,笔者不想通过一种循规蹈矩的方式来学习:先学Dart语言,然后学习Flutter的基本使用,再到实践应用这样的步骤。这样的方式有点无趣且效率较低。 笔者觉得对于已经有Android基础的来说,通过类比Android的方式来学习Flutter,掌握核心基础概念后,直接开发实践应用,在这个过程...
除了将FlutterActivity更改为FlutterFragmentActivity之外，我还必须在build.gradle中添加implementation 'android...
