matchRoute function

RouteMatch matchRoute(List<String> patterns, String path)

Matches path against patterns, returning the first match. Patterns use :name segments for parameters. Pure and DOM-free.

Implementation

RouteMatch matchRoute(List<String> patterns, String path) {
  final pathSegs = _segments(path);
  for (final pattern in patterns) {
    final patSegs = _segments(pattern);
    if (patSegs.length != pathSegs.length) continue;
    final params = <String, String>{};
    var ok = true;
    for (var i = 0; i < patSegs.length; i++) {
      final p = patSegs[i];
      final v = pathSegs[i];
      if (p.startsWith(':')) {
        params[p.substring(1)] = Uri.decodeComponent(v);
      } else if (p != v) {
        ok = false;
        break;
      }
    }
    if (ok) return RouteMatch(pattern, path, params);
  }
  return RouteMatch('', path);
