Digital Ink Recognizer, candidate score always 0, flutter adnroid

[homamAboAhmad]

I tried the example, and it has the same problem

Title:
Digital Ink Recognizer, candidate score always 0, flutter adnroid

Discription:
when app check, recognize text, it gives list of candidate,
the candidate has a text - candidate.text - which has no problem, and has a score - candidate.score - which always 0.0 (this is the problem)

To Reproduce:

• before test edit code in recognizeText function to to show score with text
• from for (final candidate in candidates) { _recognizedText += '\n${candidate.text}'; } to for (final candidate in candidates) { _recognizedText += '\n${candidate.text}-${candidate.score}'; }
• in example app, go to Digital ink recognition
• download the language model
• after finish draw the letter you want to recognize Like H
• the press read text so see results
• you can see letters with 0.0 scores always
• tested on android device
  Expected behavior: the score should not alway be zero

Platform:
OS: Android
Device: Samsung Note 9
Flutter 3.10.5 • channel stable
Dart 3.0.5
plugin version: google_mlkit_digital_ink_recognition: ^0.10.0

Hi @homamAboAhmad
Thanks for opening the issue.
Returning 0 will be from the native API.
This package works on that.
I hope it helps you.

@bensonarafat thanks for reply, in logs from native, score is not zero, and works fine

I am having the same issue. When looking at the native logs I get the following output:

I/native  ( 4564): I0520 15:42:39.528931   17827 tf_recognizer.cc:293] best result: '母'  score: -348.23

Which shows a recognition score of -348.23; however, when I check the recognition candidate's score directly it always responds with 0.
