Multiple flutter views seems to interfere with each others graphics context. #17688
Description
I have only tried this on iOS.
I created an iOS project creating two distinct FlutterViewControllers, each showing the same image (using new Image.asset("assets/a.jpeg")).
The image is garbled in the second view.
Attaching a screen recording showing the problem (the two views should show the same image).
The code instantiating the FlutterViewController is as follows:
- (void)pushFlutter1 {
NSLog(@"Pushed");
if (!_flutterViewController1) {
_flutterViewController1 = [[FlutterViewController alloc] initWithProject:nil nibName:nil bundle:nil];
messageChannel = [FlutterBasicMessageChannel messageChannelWithName:@"channel"
binaryMessenger:_flutterViewController1
codec:[FlutterStandardMessageCodec sharedInstance]];
[_flutterViewController1 setInitialRoute:@"1"];
UINavigationController* __weak weakSelf = self;
_flutterViewController1.edgesForExtendedLayout = UIRectEdgeNone;
[messageChannel setMessageHandler:^(id message, FlutterReply reply) {
[weakSelf popViewControllerAnimated:YES];
NSLog(@"Popping");
reply(@"");
}];
}
NSAssert([self navigationController], @"Must have a NaviationController");
[[self navigationController] pushViewController:_flutterViewController1 animated:YES];
}(and similarly for the second view).
