Answer 1

You can try this to show in the widget

Image.memory(your_uin8listBytes)

or

MemoryImage(your_uin8listBytes)

If you are sending the uin8list to firebase storage you can use

putData(your_uin8listBytes)

instead of

putFile(File)

and set metadata

 SettableMetadata(contentType: 'image/$fileType')

Answer 2

To upload uint8List to REST server you can do it with

MultipartFile.fromBytes(String field, List<int> value, {String? filename, MediaType? contentType})
