List<String> splitArgs(String string)

Attempt to split arguments while taking into account quotes

Implementation

// @internal

  final out = <String>[];
  var cur = '';
  var inQuoteStr = '';
  // print('starting from: $string');
  for (var i = 0; i < string.length; i++) {
    final inQuoteCtx = inQuoteStr.isNotEmpty;
    final char = string[i];
    final curCharIsQuote = char == '"' || char == "'";
    if (!inQuoteCtx && curCharIsQuote && i < string.length - 1) {
      // print('starting quote, taking ${char + string[i + 1]}');
      // starting a quote
      // cur += string[i + 1];
      inQuoteStr = char;
      continue;
    }
    if (inQuoteCtx) {

        // print('terminating quote');
        inQuoteStr = '';

        cur = '';
        continue;
