[Bug]:有没有个比较稳定的版本，总是卡死

### 请描述遇到的问题，以及您所期望的正确的结果

func pushFlutterRoute(_ options: FlutterBoostRouteOptions!) {
guard let navigationController = topViewController()?.navigationController,let engine = FlutterEngineManager.shared.engine else { return }
let pageName:String = options?.pageName ?? ""
let uniqueId:String = options?.uniqueId ?? pageName
let arguments: [String: Any] = options?.arguments as? [String: Any] ?? [:]
let opaque:Bool = options?.uniqueId as? Bool ?? false

let vc:FBFlutterViewContainer = FBFlutterViewContainer()
vc.setName(pageName, uniqueId: uniqueId, params: arguments, opaque: opaque)
// 是否伴随动画
var animated = true
if let animatedValue = options.arguments["animated"] as? NSNumber {
animated = animatedValue.boolValue
}
// 是否是以 present 的方式打开
let present = (options.arguments["present"] as? Bool ?? false) || !options.opaque
if present {
navigationController.present(vc, animated: animated) {
options.completion?(true)
}
} else {
navigationController.pushViewController(vc, animated: animated)
options.completion?(true)
}
}

### 请说明如何操作会遇到上述问题

func pushFlutterRoute(_ options: FlutterBoostRouteOptions!) {
guard let navigationController = topViewController()?.navigationController,let engine = FlutterEngineManager.shared.engine else { return }
let pageName:String = options?.pageName ?? ""
let uniqueId:String = options?.uniqueId ?? pageName
let arguments: [String: Any] = options?.arguments as? [String: Any] ?? [:]
let opaque:Bool = options?.uniqueId as? Bool ?? false

let vc:FBFlutterViewContainer = FBFlutterViewContainer()
vc.setName(pageName, uniqueId: uniqueId, params: arguments, opaque: opaque)
// 是否伴随动画
var animated = true
if let animatedValue = options.arguments["animated"] as? NSNumber {
animated = animatedValue.boolValue
}
// 是否是以 present 的方式打开
let present = (options.arguments["present"] as? Bool ?? false) || !options.opaque
if present {
navigationController.present(vc, animated: animated) {
options.completion?(true)
}
} else {
navigationController.pushViewController(vc, animated: animated)
options.completion?(true)
}
}

### 在下面填入关键复现代码

func pushFlutterRoute(_ options: FlutterBoostRouteOptions!) {
guard let navigationController = topViewController()?.navigationController,let engine = FlutterEngineManager.shared.engine else { return }
let pageName:String = options?.pageName ?? ""
let uniqueId:String = options?.uniqueId ?? pageName
let arguments: [String: Any] = options?.arguments as? [String: Any] ?? [:]
let opaque:Bool = options?.uniqueId as? Bool ?? false

let vc:FBFlutterViewContainer = FBFlutterViewContainer()
vc.setName(pageName, uniqueId: uniqueId, params: arguments, opaque: opaque)
// 是否伴随动画
var animated = true
if let animatedValue = options.arguments["animated"] as? NSNumber {
animated = animatedValue.boolValue
}
// 是否是以 present 的方式打开
let present = (options.arguments["present"] as? Bool ?? false) || !options.opaque
if present {
navigationController.present(vc, animated: animated) {
options.completion?(true)
}
} else {
navigationController.pushViewController(vc, animated: animated)
options.completion?(true)
}
}

### 复现的平台

iOS

### Flutter SDK版本

3.27.1

### FlutterBoost版本

4.6.5

### 是否延迟初始化FlutterBoost

No

### 解决方案

Start with the pushFlutterRoute entry point shown in the report and reproduce the freeze on iOS using Flutter SDK 3.27.1 and FlutterBoost 4.6.5. The report does not name a file or test; first establish precise steps and capture the conditions under which navigation hangs. Done means the freeze has a reproducible cause and the relevant behavior is verified against a stable version.
