Flutter/Dart: Extract numbers from an image (offline)

I have an image uploaded by the user, which can be viewed enter image description here. My goal is to extract the number present inside the image and utilize it later within the application. Unfortunately, the libraries I have tried so far did not produce the desired results for my specific use case.

I would greatly appreciate any guidance or suggestions on how to effectively extract the number from the image. If someone could provide a code example or recommend a different library that might be more suitable for this task, it would be immensely helpful.

Thank you in advance for your assistance!
