How to encode message into an image? #
- Create an
import 'dart:io'; ... File file = File(...); // the key is use to encrypt your message with AES256 algorithm EncodeRequest request = EncodeRequest(file.readAsBytesSync(), "your_message", key: "your_key");
// for async Uint8List response = await encodeMessageIntoImageAsync(request); //or for sync Uint8List response = encodeMessageIntoImage(request);
- Display encoded image
import 'package:flutter/material.dart'; ... Image.memory(response);
How to decode message from an image? #
- Create a
import 'dart:io'; ... File file = File(...); // the key is use to decrypt your encrypted message with AES256 algorithm DecodeRequest request = DecodeRequest(file.readAsBytesSync(), key: "your_key");
// for async String response = await decodeMessageFromImageAsync(request); //or for sync Uint8List response = decodeMessageFromImage(request);
- Display message
import 'package:flutter/material.dart'; ... Text(response);
