I created a new Flutter project following your steps, targeted Android 13 in Here is the repository: https://github.com/shliama/camera_plugin_android_13_issue Let me know if you need any specific info, but I don't run anything special - it is reproduced if you build the app on both Mac & Windows. flutter doctor -v |

Investigating a bit - List<EncoderProfiles.VideoProfile> videoProfiles = recordingProfile.getVideoProfiles();This is returning an empty list as I did a test and if I comment out and use the "deprecated" code for determining the resolution, the camera works again Looks like the change for this was introduced because @shliama what device have you confirmed the issue on? For me, I can reproduce the issue on my Pixel 5 after upgrading it to android 13 today. Could this be a bug in android 13? From the docs:
But when I try to print the result of getAll, it's always a null list: |
|
@acoutts I reproduced it on my Pixel 4a 5G but also on AVD with emulated camera. So I'm pretty sure it's not a device specific but Android 13 issue. |
|
I have the same problem on my Pixel 6 Pro after I upgraded to Android 13, worked fine before. Glad you are working on this, it is blocking me right now :) |
|
same issue with my pixel 6 |
|
Please try my quick fix here: camera_android:
git:
url: https://github.com/bottlepay/plugins.git
path: packages/camera/camera_android
ref: e1a4dba770da9bc3cf9f858bac6837083f8b9059I just commented out the "new" method so it's using the deprecated one. It does make the camera work again but I'm not sure how the permanent fix should work. Hopefully someone with more knowledge of the camera api can chime in. |
|
@acoutts thanks , should i add this along side regular camera dependency ? (pub get complains about dependency mismatch) , or should i do : |
|
The easiest way is to just add it under https://dart.dev/tools/pub/dependencies#dependency-overrides |
|
yes , just did that , it works , |
|
@acoutts should this work for older android versions ? |
|
seems that it doesnt work for android 12 |
|
I just tested it on a pixel 6 android 12 and it works for me.. |
|
Tested it on pixel 3 with android 12 , will reverify again tomorrow, thanks! |
|
@acoutts you are right , didnt work due to a different issue |
|
@elmar001 Thank you. But i meant the version(s) of the camera package itself. Your fix is from October 10, this means version 0.10.0+3. But what about e.g. the current version 0.10.3? |
|
|
The issue is still not resolved in 0.10.3. |

why is this issue closed??? |

Looks like it is fixed with the workaround from this: |
|
It's released: https://pub.dev/packages/camera_android
Just run ’pub upgrade’

@PerLycke why havent they updated https://pub.dev/packages/camera package |
Because it's not needed. It's a transitive dependency which got an incremental update and will be updated if you run the upgrade command. |
|
I confirm upgrading |
What's your minSDK version? |
21 but it shouldn't be relevant. |
|
@mauriziopinotti when 0.10.4 release?? |
Version 0.10.4 of camera_android has been released (not to be confused with camera). |
|
Why is this issue closed? The camera plugin still doesn't work, I don't want to use camera_android. |
You don't need to use camera_android explicitly, it's already used by camera package, because it's a transitive dependency. All you need to do is to run |

* Added the movenet tflite model * Added Keypoint model to hold output data * Added logic for interpreting images & viewing results - a callback passed to `startImageStream` in CameraView that converts the pixel data from the camera into a format the TFLite plugin can use. - KeypointViewer, a CustomPaint that paints circles for each keypoint. - a ValueNotifier to tie the two together. * Added a profile launch config * Added workaround for Android 13 bug The bug will be fixed in an upcoming build see: flutter/flutter#109769 * Commit automatic changes made by running a build * Encapsulate inference & model loading in classes I made a separat class for extracting the model from the asset bundle, saving locally and holding on to the file path. I moved the code for running inference to a separate class. The code is now in InferenceRunner. For now this is using the Interpreter just as the CameraView was but in the next step the interpreter will be created in an Isolate and the runner will send and recieve message with the Isolate. I also added an extension on CameraImage that converts the image data to the form that the input tensor needs. The extension is just for readability. We now combine the model loading and inference setup in the MainScreen then the CameraView asks the InferenceRunner to run inference on each image that the image stream receives. * Move views into separate folder for findability * Add isolate based implementation of InferenceRunner Co-authored-by: Trevor Davis <tzendou@gmail.com> --------- Co-authored-by: Trevor Davis <tzendou@gmail.com>

You could try |
Not working，I don't know if it only works on application instead of plugin, I've try to clean and rebuild, but still not working, should I file a new issue for tracking? |
Just do a pub upgrade, camera_android is a transitive dependency. After upgrading your pubspec.lock should look like this: |
My pubspec.lock camera_android: |

…ower than 12 (#4635) The the solution of the issue flutter/flutter#109769 in the #7073 causes a crashes when the Android SDK version is lower than 31, due to EncoderProfiles not being found on these devices. This issue was solved putting the EncoderProfiles declaration after the check for SDK version. based on flutter/plugins#7073 by @camsim99. Fixes flutter/flutter#109769 in Android lower than 12.
