model seems like loaded but nothing on the screen after some bugs #65

Jaemani · 2024-10-15T07:53:49Z

preinstall, bug fixed
run terminal at yolo-flutter-app/example.
required flutter create, ran it.

win32 version caused error,
clean cache&flutter get+ flutter pub upgrade win32 not worked,
manually upgraded from 3.1.4 to 5.6.0. solved it.
flutter minimum required kotlin > 1.7.0, but now 1.5.10 changed to "ext.kotlin_version = '1.7.10'".
requierd compileSdkVersion 34, so changed compileSdkVersion 33 to 34
transforms-3/...transformed/jetified-core-ktx-1.13.1-api.jar!/META-INF/core-ktx_release.kotlin_module
metadata is 1.8.0, expected 1.5.1
changed back to "ext.kotlin_version = '1.5.10'". and flutter required 1.7.10 again.
so fix again to "ext.kotlin_version = '1.7.10'"

android
build successful.
uncomment the object detector, and choosed builted-in .tflite model.
Not working,
it was black when it is asking about permission, but
only white blank screen after request permission.
when click button just show 1,0,1,0 at terminal.

macOS & iOS simulator
build successful.
uncomment the object detector, and choosed builted-in .mlmodel model.
Not working,
only white screen after request permission.

also added loading placeholder code as github page, but no any letters shown, only blank white screen.

@Jaemani it seems like you're encountering issues with the app displaying a blank screen after loading the model. Please ensure you're using the latest version of the Ultralytics package and verify that all dependencies are correctly updated. If the issue persists, consider checking the permissions and reviewing the logs for any additional errors. For further assistance, you can explore our documentation at https://docs.ultralytics.com. If you have more questions, feel free to ask!

got this when flutter pub upgrade
No dependencies changed.
16 packages have newer versions incompatible with dependency constraints.

at first I couldn't get from flutter pub deps, so I tried
sudo rm -Rf /Users/<username>/.pub-cache
sudo rm -Rf .packages
and
flutter pub get

Jaemani · 2024-10-15T19:08:00Z

I'm just wondering that I don't know why I'm having problems even though I've clone from github and didn't touch anythinng

Jaemani · 2024-10-15T19:51:24Z

also tried on Windows OS, but got exactly same bugs, including this:

after changed to "ext.kotlin_version = '1.7.10'". got

.gradle/caches/transforms-3/0d01aa93113a93dc848bd76abf9dde3c/transformed/jetified-core-ktx-1.13.1-api.jar!/META-INF/core-ktx_release.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.5.1.

and then when changed back to "ext.kotlin_version = '1.5.10'"
it suddenly compiled. but same black screen.

and flutter required 1.7.10 again.
so fix again to "ext.kotlin_version = '1.7.10'"

all of the result and the flow are the same..

Jaemani · 2024-10-16T08:46:04Z

Downgraded to flutter 3.22.0-stableand no 1~4 bug occurred !
but still same blank screen..

would you tell me if the SDK version was the problem, did I used correct flutter version?

pderrenger · 2024-10-16T12:22:32Z

Please ensure you're using the latest version of the Ultralytics package and verify all dependencies are updated. If the issue persists, check the compatibility of your Flutter version with the package. For further guidance, visit our documentation at https://docs.ultralytics.com.

Jaemani · 2024-10-17T10:08:56Z

@pderrenger Please, would you just tell me the version and dependency? I can not find any documentation about flutter or flutter environment.

pderrenger · 2024-10-17T20:50:24Z

Please ensure you're using the latest version of the Ultralytics package and check the compatibility with your Flutter SDK. For detailed guidance, visit our documentation at https://docs.ultralytics.com.

sruizhuenei · 2024-11-04T18:24:04Z

I think @pderrenger is just a bot...always response the same...LOL
@Jaemani I'm facing an error in my app...the example app works with my yolo v8 model. I'm trying to classify images in real time with the component UltralyticsYoloCameraPreview selecting an image from the gallery and classify it work OK.

:/

pderrenger · 2024-11-05T03:23:11Z

Please ensure you're using the latest version of the Ultralytics package. If the issue persists, try checking the configuration of UltralyticsYoloCameraPreview for real-time classification. If you need further assistance, feel free to ask!
