Error: Called start() while already started!
Hi, @navaronbracke
What could be the reason of this error in the ErrorBuilder?
Called start() while already started!
It doesn't happen all the times, it happens for example when I restart the app when I was in a screen that is using the MobileScanner, and open the screen again.
Mostly happens in Debug mode.
I have also issues when I navigate from a screen that has a Scanner in it to a new screen with the Scanner using push, so in the screens stack there are multiple instances with MobileScanner.
Calling the "stop()" before doesn't help.
How can I avoid this?
How can I check if MobileScanner was already started?
How can I actually create and use multiple instances of the Scanner?
Is this related to using hot reload? If so, we have an open issue for that https://github.com/juliansteenbakker/mobile_scanner/issues/773
The underlying issue is that we should just ignore duplicate calls to the start method, when the controller is already starting. One example of that, is a lifecycle switch initiated by the permission dialog.
I have a PR that should fix this issue, https://github.com/juliansteenbakker/mobile_scanner/pull/1086 but I need to test it on our supported platforms.
If you're willing to test out that fix, in relation to app lifecycle changes on our supported platforms (Android, iOS, MacOS, Web) that would be very helpful in proving that that PR fixes the issue.
When it comes to using multiple instances of the MobileScanner widget, you probably need to stop or dispose the old controller before going to a new screen. We do not support multiple instances at once, since there is only one connection to the camera output at a given time.
Hey @navaronbracke- I don't think it's related to hot reloads. It happens for me, even when just opening for the first time. Specifically I copied over the code from example repo, specifically the BarcodeScannerWithOverlay.
I have not changed any code yet. But is it flaky, because initially it worked fine.
@simplenotezy I ran a test on the branch for the "already started" issue.
I did see that hot restart is broken when the camera preview is in use, but otherwise I didn't have any issues.
1) Normal use (no hot reload or hot restart) works fine
2) Hot restart (shift + r)
- does not work when invoked when the camera preview is running (camera preview is a black screen, controller cannot be started)
- does work when the camera is not in use (i.e. no active MobileScannerController is being used)
3) Hot reload (r)
- works when the camera is not in use
- work when the camera is in use
Only the hot restart issue when the preview is open, but yes there definitely is an issue here.

hi!!
is there any fix for this error? @navaronbracke
Main issue is that we cannot stop/restart it. There should be a way to "restart" native camera plugin...in case of such exception. As now if this happens, disposing of current controller doesnt help, and we cannot start new one.
I had the same problem。
It reports an error ： MobileScannerException: code genericError, message: Called start() while already started

This is probably still affecting people, but we don't have many "thumbs up" for the original post. I do have a WIP patch for his bug, but I should probably clean it up and test it.
I "fixed" it in my own branch: https://github.com/navaronbracke/mobile_scanner/commit/78236fab0c0c667820388bd2a8cdc3b6d4f320c6
@radvansky-tomas That is only for iOS and not for Android / MacOS or web, though.
Yeah i didnt have that issue there though

Having this issue and it's not really clear what can be done to resolve it. My expectation here is that any initialization logic is idempotent / fails gracefully
What my patch aims to do is the following: if we already started we should not throw an error, period. Just do nothing instead, since starting an already started camera is redundant.
Although, stopping and restarting the camera is another option. What would you prefer?
@navaronbracke I'm not sure if this is the cause of all cases showing this error.
But, basically I solved the problem related to this based on the workaround mentioned here (by using "VisibilityDetector"): https://github.com/juliansteenbakker/mobile_scanner/issues/1002
By stopping the scanner when navigating to another screen that may use the Scanner/Camera while the scanner is still active on the previous screen in the screen stack. And activating it again when returning to the screen.
It's a bit tricky, but it works.
Thats not solving underlaying issue that native controller is not related to dart one. So if iOS / Android "camera" is still active and dart has no clue about it it fails. We need to handle this situation gracefully, recreate controller and attach to dart counterpart.
this issue is still happening in both android and ios. stop() doesn't do anything , also does't matter what you do if you pop the screen that has the mobile_scanner widget and push it again ,the error is still there, there is no way to reset it.
I think this issue will be fixed in v6.0.9. If not, please let me know.
I think this issue will be fixed in v6.0.9. If not, please let me know. Thanks.
What does it mean? So I won't need the "VisibilityDetector" workaround anymore when I navigate to a new screen that also has a MobileScanner instance, while the previous screen still has an active instance of MobileScanner? Do I need to stop the controller or anything else before navigate to the new screen?
Do I need to stop the controller or anything else before navigate to the new screen?
Yes you should stop/dispose the controller before navigating and start it again on the new screen. We do not yet support multiple MobileScannerControllers running at the same time
@override
void didChangeAppLifecycleState(AppLifecycleState state) async {
// If the controller is not ready, do not try to start or stop it.
// Permission dialogs can trigger lifecycle changes before the controller is ready.
if (!scannerController.value.isInitialized) {
return;
}
switch (state) {
case AppLifecycleState.detached:
case AppLifecycleState.hidden:
case AppLifecycleState.paused:
return;
case AppLifecycleState.resumed:
// Restart the scanner when the app is resumed.
// Don't forget to resume listening to the barcode events.
unawaited(scannerController.start());
case AppLifecycleState.inactive:
// Stop the scanner when the app is paused.
// Also stop the barcode events subscription.
if (scannerController.value.isInitialized) {
unawaited(scannerController.start());
}
@override
void initState() {
WidgetsBinding.instance.addObserver(this);
scannerController = MobileScannerController();
// Finally, start the scanner itself.
if (scannerController.value.isInitialized) {
unawaited(scannerController.start());
}
super.initState();
}
@override
void dispose() async {
WidgetsBinding.instance.removeObserver(this);
super.dispose();
await scannerController.stop();
await scannerController.dispose();
}
i solved it by just add this line of code if (scannerController.value.isInitialized) { unawaited(scannerController.start()); }
I think this issue will be fixed in v6.0.9. If not, please let me know.
I'm still facing this issue
