Google would have helped you : LMGTFY In short: your context change and photo_view has been disposed. |
|
I had this error too and could not find any answer on google which fixed it. But I figured out after switching flutter channel to stable (I was using channel master), you don't get the error anymore. |
|
I have also encountered this problem. I use the master version of flutter. |
|

The same on Flutter 2.9.0-1.0.pre498 (master channel) |

I have the same error. |
|
Me too. Is it possible to do the new release soonish as the PR with the fix is already merged, right? |
|
Any hope for this to be fixed soon, or at least give a timeframe? Updating to the latest stable branch breaks this. |

When I open Photoview and dont do anything bot pops the screen I get an error:
FlutterError (Looking up a deactivated widget's ancestor is unsafe.
At this point the state of the widget's element tree is no longer stable.
To safely refer to a widget's ancestor in its dispose() method, save a reference to the ancestor by calling dependOnInheritedWidgetOfExactType() in the widget's didChangeDependencies() method.)
If I triggers some events, e.g. panning, scaling ,it goes well.
