How to convert Text to Binary in dart (flutter)?

Question

I'm trying to develop an app to convert text to binary (and vice versa) in dart language. It'll be my first flutter app. I found dart:convert library can do this but I still don't know how to make it work. Could use some help. Thanks!

https://api.flutter.dev/flutter/dart-core/String/codeUnits.html please use it.

or

https://pub.dev/packages/binary_codec library will help you as well you can use it like this :


  /// Encode the generated data
  Uint8List encoded = binaryCodec.encode(exampleObject);

  /// Decode the encoded data
  var decoded = binaryCodec.decode(encoded);

  /// Check if they are the same
  if (exampleObject.toString() == decoded.toString()) {
    /// They should be the same
    print('Success');
  } else {
    /// Else theres a bug in the library
    /// Please send the [exampleObject] that leads here and on which 
    /// platform you are to the author of this library (stefan.zemljic@gmx.ch)
    print('Wait... What???');
  }

`String.codeUnits` returns a UTF-16 representation of the string. If using a binary format, I would strongly recommend against using that if possible since that means endianness becomes relevant, which might entail adding a BOM. For binary interchange, prefer UTF-8. — jamesdlin, Sep 20 '20 at 18:40
