在web页面对回调进行处理
@Override
public void onBackPressed() {
FlutterBrowserManager.OpenListener authListener = FlutterBrowserManager.getInstance().getOpenListener();
if (authListener != null) {
Logger.e("colose","onBackPressed1");
authListener.onClose();
Logger.e("colose","onBackPressed2");
}
super.onBackPressed();
}
在使用的时候就可以监听返回按键了
FlutterBrowserManager.getInstance()
.openBrowser(mContext, url, object : FlutterBrowserManager.OpenListener {
override fun onClose() {
// 监听到了返回
result.success(true);
}
})
