How to get hash

MrLightful commented 2 years ago

Usually, you probably want to hash the image on the backend side. You can find different packages that can be used HERE. This plugin doesn't seem to implement this functionality. It's just a decoder.

In the link above, you can also find encoder implementations for Swift and Kotlin, so I guess you can use them. Although it may take some work to integrate them into Flutter by yourself.

Edit: although there is this Dart package that does encoding. So you can use it as well.

You are right. Thanks for pointing to a Dart encoder as I currently only support decoding. Encoding is a expensive task and should be optimized and the C impl can be easily integrated leading to top perfs and costs.
