[Bug]: iOS原生跳转flutter页面，每次都是一个新的Flutter页，且来回进入和退出，第一个页面一直存在

[TomasWell]

请描述遇到的问题，以及您所期望的正确的结果

期望返回的时候能销毁

请说明如何操作会遇到上述问题

有四个页面
原生A、FlutterB、原生C、FlutterD
/course-category-page就是FlutterB页面

ABCD DCBA ABCD DCBA ABCD DCBA ABCD DCBA
来来回回进入和退出

控制台会打印

每一个uniqueId都不一样，是不是对应的就是B页面初始化了很多

这是问题1

问题2是，当C页面是个嵌套Flutter的原生页面的时候，按照上面来回操作，B页面会白屏

在下面填入关键复现代码

原生进入Flutter代码如下

• (void)goFlutterWithPageName:(NSString *)pageName arguments:(NSDictionary *)arguments {
  FlutterBoostRouteOptions *options = [[FlutterBoostRouteOptions alloc] init];
  options.pageName = pageName;
  // options.uniqueId = nil;
  options.arguments = arguments;
  options.onPageFinished = ^(NSDictionary * dic) {
  NSLog(@"onPageFinished 反向传值");//反向传值
  NSLog(@"%@",dic);//反向传值
  };
  options.completion = ^(BOOL success) {
  return;//跳转完成的回调
  };
  [[FlutterBoost instance] open:options];
  }

Flutter页面pop

• (void)popRoute:(FlutterBoostRouteOptions *)options {
  ARTFlutterViewController *vc = (id)self.navigationController.presentedViewController;
  BOOL animated = YES;
  NSNumber * animatedValue = options.arguments[@"animated"];
  if(animatedValue){
  animated = [animatedValue boolValue];
  }
  if([vc isKindOfClass:ARTFlutterViewController.class] && [vc.uniqueIDString isEqual: options.uniqueId]){
  if(vc.modalPresentationStyle == UIModalPresentationOverFullScreen){
  [self.navigationController.topViewController beginAppearanceTransition:YES animated:NO];
  [vc dismissViewControllerAnimated:YES completion:^{
  [self.navigationController.topViewController endAppearanceTransition];
  }];
  }else{
  [vc dismissViewControllerAnimated:YES completion:^{}];
  }
  }else{
  [self.navigationController popViewControllerAnimated:animated];
  }
  if (self.onPageFinished) {
  self.onPageFinished(options.arguments);
  }
  options.completion(YES);
  }

原生页面嵌套Flutter页面代码如下

• (void)dealloc {
  [self stopTimer];
  [self.flutterViewController notifyWillDealloc];
  [self.flutterViewController detachFlutterEngineIfNeeded];
  }

• (void)initView {
  self.rt_disableInteractivePop = NO;
  [[UIApplication sharedApplication] setIdleTimerDisabled:YES];
  [self.view addSubview:self.mainView];
  [self.mainView mas_makeConstraints:^(MASConstraintMaker *make) {
  make.edges.mas_equalTo(0);
  }];

  [self initViewAction];
  [self initFlutterView];
  }

• (void)initFlutterView {
  self.flutterViewController = [[ARTFlutterViewController alloc] init];
  NSString *routePath = [NSString stringWithFormat:@"/%@",self.page];
  [self.flutterViewController setName:routePath uniqueId:nil params:@{@"id":self.id_p} opaque:YES];
  [self addChildViewController:self.flutterViewController];

  [self.mainView.businessContainer addSubview:self.flutterViewController.view];
  CGRect containerFrame = self.mainView.businessContainer.frame;
  self.flutterViewController.view.frame = CGRectMake(0, 0, containerFrame.size.width, containerFrame.size.height);
  }

复现的平台

iOS

Flutter SDK版本

3.19.6

FlutterBoost版本

是否延迟初始化FlutterBoost

No
