heckofaheic

Converts HEIC into PNG/JPEG/GIF using heic2any.

Useful in case your users are uploading HEIC images to your Flutter web app that need to be displayed correctly, as HEIC is not supported by most browsers.

Web only

Getting started

1. Please download a copy of heic2any.min.js on alexcorvi.github.io/heic2any
2. Save it in your Flutter project's web folder, next to index.html
3. Link the script in your index.html, like so:

   <script src="heic2any.min.js" type="application/javascript"></script>

4. Add a new script tag to your index.html, with the following content:

   <script>
   function executeHeic2any(blob, multiple, toType, quality, gifInterval) {
   	return heic2any({
   		blob,
   		multiple: multiple,
   		toType: toType,
   		quality: quality,
   		gifInterval: gifInterval
   	});
   }
   </script>

Usage

import "package:heckofaheic/heckofaheic.dart";

Future<void> myFunction() async {
  Uint8List imageBytes = await getYourImageBytesSomehow();

  if (HeckOfAHeic.isHEIC(imageBytes)) {
    imageBytes = await HeckOfAHeic.convert(imageBytes);
  }
}
