Setup

• Web
• Others: no special setup required

Usage

import 'package:flutter_charset_detector/flutter_charset_detector.dart';

Uint8List bytes = getBytes(); // bytes with unknown encoding
DecodingResult result = CharsetDetector.autoDecode(bytes);
print(result.charset); // => e.g. 'SHIFT_JIS'
print(result.string); // => e.g. '日本語'
