Router prefix([
  1. String? prefix
])

Implementation

Router prefix([String? prefix]) {
  if (prefix != null && _routes.isNotEmpty) {
    final route = _routes.last;
    final basePath = route.path.startsWith('/')
        ? route.path.substring(1)
        : route.path;

    route.path = prefix.endsWith("/")
        ? "$prefix$basePath"
        : "$prefix/$basePath";
  }
  return this;
}
