Can the model download address in learning_digital_ink_recognition come from other locations, such as our own server?

Hi, can I change the text 'Choose image' and 'Take photo' of the InputCameraView buttons?

Thanks for listening :)

I install and open it , it has no response to any face...too bad

Can i use learning_face_detection package to fix the selfie photo orientation?

Please fix the issue. As this plugin is based on very old version of camera plugin.

Since this package uses com.google.mlkit.vision, what about license and pricing?

I want to put a condition when it finds a specific value and sends it to another page, but it does not stop sending values ​​to the page

` Future<void> _startRecognition(InputImage image) async {
   TextRecognitionState state = Provider.of(context, listen: false);

   if (state.isNotProcessing) {
     state.startProcessing();
     state.image = image;
     state.data = await _textRecognition?.process(image);
     state.stopProcessing();
   }
   ///=======
   if(state.text.length>=12){

     Navigator.push(
       context,
       MaterialPageRoute(builder: (context) => fff(state.text)),
     );

     state.stopProcessing();
     state.removeListener(() { state;});
   }`

my app use this package worked with anydevice . But when release app and run on device android 13 app crashed. please tell me if somebody know solutions. thanks

when i add this dependency google_ml_kit: ^0.7.2 it crash the project when i do the selfie segmentation.
on this below line.

SegmentationMask? mask = await _segmenter.process(image);

Hey @salkuadrat, thanks for the great work on this plugin - it's really helpful. I set up learning_translate and learning_language and they work perfectly on android. However, the iOS build is still failing. Not sure if the problem is related to this plugin or if it's my setup.

This is the error message when running flutter build ios. Same error happens using Xcode (and yes, I made sure to open xcworkspace and not xcodeproj as suggested here):

Swift Compiler Error (Xcode): No such module 'MLKit'
/Users/x/.pub-cache/hosted/pub.dartlang.org/learning_translate-0.0.4/ios/Classes/SwiftLearningTranslatePlugin.swift:3:7

In Xcode, it looks like this module doesn't exist either, however, there's one called "GoogleMLKit" (in case this has something to do with it (?)):

I'd greatly appreciate any help on this.

Hi,

First off thanks for the libraries, they're pretty awesome!

I was playing around with the digital ink recognition part of the example app and noticed that the scores of every RecognitionCandidate returned was null.

Reproduction steps

1. Add the following printout statement on line 80 of digital_ink_recognition.dart:

for (final candidate in state.data) {
  debugPrint(
      '$LearningDigitalInkRecognition: _startRecognition : text=${candidate.text} : score=${candidate.score}');
}

2. Launch the example app
3. On the main screen select "Digital Ink Recognition"
4. Draw a "W" on the canvas
5. Tap the "Start Recognition" button

Expected output

• A list of RecognitionCandidate, each with member variables text (String) and score (double?) set to non-null values when appropriate

Actual output

• A list of RecognitionCandidate which all have the variable text populated with a meaningful value but score is null
• As the log below shows, the first candidate at least should have a score as we can see it being printed out in both tf_recognizer.cc and helper.cc

Hi!
Great work! On android, Selfie segmentation worked really good 😄

By the way, on ios, I got this error message when selecting image.
Hope this will help.

Hi,
how i can invoke delete offset point,
thanks

Face detection working fine on android but doesn't work on ios (tested on both Mac M1 & Intel)

Hello,
thanks for the lib and the compiled apk.
Unfortunately on my Samsung SM-T500 (Galaxy Tab a7) the image recongnition doesn't work using the live camera preview.
It works using camera from gallery.
I'm using learning_face_detection: ^0.0.3 and camera: ^0.9.4+5
Also I tried to add "implementation 'com.google.mlkit:face-detection:16.1.3'" in build.gradle with no success.

To be honest this seems related to this device only. On my Xiaomi phone it works. What is very strange is that on this tablet every mlkit package I tried on pub.dev doesn't work with this tablet. Could it be related to the camera plugin then? Thanks

I have this problem only on iOS devices when I run the app:

" Runner[2241:317680] The selected imageFormatGroup is not supported by iOS. Defaulting to brga8888 "

Can someone help me?

update plugin and recognize the image by image path, let the user use any camera plugin
