connectSurfaceToRenderer() should only be called when flutterRenderer and getSurfaceTexture() are non-null. com.idlefish.flutterboost.containers.FlutterBoostActivity.C(FlutterBoostActivity.java:163)

当flutter端存在内存泄漏的时候，发现的这个问题。有监听器在页面dispose后调用了setState；

由于flutterboost中FlutterTextureHooker存在反射调用FlutterTextureView；而FlutterTextureView类被混淆而导致反射逻辑失败，导致FlutterTextureView类的attachToRenderer方法中connectSurfaceToRenderer被执行，而此时绘制层已经为空，所以报错：connectSurfaceToRenderer() should only be called when flutterRenderer and getSurfaceTexture() are non-null

Start with FlutterBoostActivity.java at line 163 and trace FlutterTextureHooker’s reflective access to FlutterTextureView.attachToRenderer. Check the connectSurfaceToRenderer call and the reported null-state path; done means the call is not reached when flutterRenderer or getSurfaceTexture() is null and the reported exception no longer occurs.
