parseQueryString function

Map<String, String> parseQueryString(String query)

Parse query string to map (and back). Roadmap #168.

Implementation

Map<String, String> parseQueryString(String query) {
  final Map<String, String> out = <String, String>{};
  if (query.isEmpty) return out;
  for (final String pair in query.split('&')) {
    final int eq = pair.indexOf('=');
    if (eq != -1) {
      out[Uri.decodeComponent(pair.replaceRange(eq, pair.length, ''))] = Uri.decodeComponent(
        pair.replaceRange(0, eq + 1, ''),
      );
    } else if (pair.isNotEmpty) {
      out[Uri.decodeComponent(pair)] = '';
    }
  }
  return out;
}
