Hot Restart generate exception #41

Open guilhermedaldim opened 2 years ago

guilhermedaldim commented 2 years ago

Another problem I noticed, is that in debug when calling Hot Reload with the camera open, I wait for the event end and when trying to open the camera again I get the following: PlatformException (PlatformException(ALREADY_INITIALIZED, Camera is already initialized, null, null)).

I believe it is the dispose() call that is not being made in this case, because when to close and open the camera again, it works normally.

Can you please add which branch or version you are on?

guilhermedaldim commented 2 years ago

I'm test in develop branch

jhoogstraat commented 2 years ago

Normally the preview should just continue, independent of hot reloads. Maybe if the widget tree is rebuilt...

Sorry man the problem occours with Hot Restart

jhoogstraat commented 2 years ago

This seems to be a more general issue with hot restart (related issue)

I've experienced this as well but never had this problem on the flutter_barcode_scanner, so I would think it's something that can be fixed.

Any news on this? It's stil happening on develop

CordMemescape commented 2 years ago

I can confirm that this is still an issue using ^2.0.0-dev.2.

If you happen to have the camera active - scanning for a barcode - an exception is thrown when your app is restarted via the debugger and you return to the view with the BarcodeCamera() widget. The following is displayed:

Error: PlatformException(ALREADY_INITIALIZED, Camera is already initialised, null, null)

If you navigate away from the view and back again, the camera reinitialises correctly and you can continue scanning.
