-(void)test01{
    //創(chuàng)建FlutterViewController
    FlutterViewController* flutterViewController = [[FlutterViewController alloc] init];
    self.fc = flutterViewController;
    //添加進view
    [self.view addSubview:flutterViewController.view];
    flutterViewController.view.frame = CGRectMake(0, 60, 310, 600);
}

注意一點 此時flutter解釋器獲取不到view的狀態(tài)變化

需要手動調(diào)用FlutterViewController 的相關方法 通知flutter解釋器

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [self.fc viewWillAppear:animated];
}
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    [self.fc viewDidAppear:animated];
}
-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    [self.fc viewWillDisappear:animated];
}
-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:animated];
    [self.fc viewDidDisappear:animated];
}
