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

Screenshots If applicable, add screenshots to help explain your problem.

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.

This issue is stale because it has been open for 30 days with no activity.
