Illegal percent encoding in URI

[rounce]

when QR.settings.autoRestoration and there's unicode characters in url.

Non-fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: Invalid argument(s): Illegal percent encoding in URI
       at Uri.decodeComponent(dart:core)
       at QRouterDelegate.setNewRoutePath(router_delegate.dart:99)
       at RouterDelegate.setRestoredRoutePath(router.dart:1294)
       at _RouterState._processParsedRouteInformation.<fn>(router.dart:714)

Looks like "configuration" variable is not encoded (Uri.encodeFull).

Worked around the problem with this code:

    try {
      configuration = Uri.decodeFull(configuration).toString();
    } catch (_) {
    }
