Start the program and initialize flutter_foost with an error, but there is no crash. Then open a Flutter page through Flutter_foost, which lags and has no response
在下面填入关键复现代码
let vc:FBFlutterViewContainer = FBFlutterViewContainer() vc.setName(options.pageName, uniqueId: options.uniqueId, params: options.arguments,opaque: options.opaque)

In the above stack trace, there is clear an re-entrance of method flutter::PlatformViewIOS::SetOwnerViewController(fml::WeakNSObject<FlutterViewController> const&) (in Flutter) (platform_view_ios.mm:84)
The implementation of this method
void PlatformViewIOS::SetOwnerViewController(__weak FlutterViewController* owner_controller) {
FML_DCHECK(task_runners_.GetPlatformTaskRunner()->RunsTasksOnCurrentThread());
std::lock_guard<std::mutex> guard(ios_surface_mutex_);
if (ios_surface_ || !owner_controller) {
NotifyDestroyed();
ios_surface_.reset();
accessibility_bridge_.Clear();
}
std::mutex is not reentrant.
It seems a bug in the flutter engine itself? As it starts to appear after we recently upgraded the flutter engine to 3.27.3
You can temporarily fix it by disabling the warmUpEngine @zhaolijiu
let options = FlutterBoostSetupOptions.createDefault()
options?.warmUpEngine = false
FlutterBoost.instance().setup(
application,
delegate: self,
callback: { engine in /* ... */ },
options: options
)

it works for me

您可以通过禁用 warmUpEngine 来暂时修复此问题@zhaolijiu

Thank you. That's it. White screen time is acceptable
I found one consistent way (at least on my phone) to reproduce this issue. In "Settings | Accessibility" Turn on the "Switch Control" or "Voice over". And the example app of the flutter_boost will hang on launch.
Probably related to the following code in FlutterViewController
bool enabled = _isVoiceOverRunning || UIAccessibilityIsSwitchControlRunning();
// If this is enabled, the app will hang
- (void)onAccessibilityStatusChanged:(NSNotification*)notification {
if (!_engine) {
return;
}
auto platformView = [_engine.get() platformView];
int32_t flags = [self accessibilityFlags];
#if TARGET_OS_SIMULATOR
// There doesn't appear to be any way to determine whether the accessibility
// inspector is enabled on the simulator. We conservatively always turn on the
// accessibility bridge in the simulator, but never assistive technology.
platformView->SetSemanticsEnabled(true);
platformView->SetAccessibilityFeatures(flags);
#else
_isVoiceOverRunning = UIAccessibilityIsVoiceOverRunning();
bool enabled = _isVoiceOverRunning || UIAccessibilityIsSwitchControlRunning();
if (enabled) {
flags |= static_cast<int32_t>(flutter::AccessibilityFeatureFlag::kAccessibleNavigation);
}
platformView->SetSemanticsEnabled(enabled || UIAccessibilityIsSpeakScreenEnabled());
platformView->SetAccessibilityFeatures(flags);
#endif
}
OK, from the code. This will hang in simulator, too.

It solved my problem. Thank you.
