How can an image be included as a parameter in a URL when sending a GET request?

You can include an image as a parameter in a URL when sending a GET request by converting the image to a Base64 string and passing this string as a parameter.

However, keep in mind that URLs have length limitations (usually around 2000 characters), so this method is only suitable for small images.

Example in Flutter:

import 'dart:convert';
import 'dart:io';

void main() async {
  // Read image from file
  final bytes = await File('path_to_image.png').readAsBytes();

  // Encode to Base64
  final base64Image = base64Encode(bytes);

  // Encode for URL
  final encodedImage = Uri.encodeComponent(base64Image);

  // Form URL with parameter
  final url = 'https://example.com/api?image=$encodedImage';

  print(url);
}

It is better to use a POST request with a request body to transmit images, to avoid URL limitations.
