Error while executing code

[johnfriend]

Please find below the error message that I have received when I used the example file

Invalid argument(s): widget.routeName must be a String beginning with forward slash (/)

The relevant error-causing widget was:
LeviSplash file:///Users/*/Desktop/Flutter//lib/main.dart:7:13
When the exception was thrown, this was the stack:
#0 _SplashScreenState.initState (package:splashscreen/splashscreen.dart:86:7)
#1 StatefulElement._firstBuild (package:flutter/src/widgets/framework.dart:4765:58)
#2 ComponentElement.mount (package:flutter/src/widgets/framework.dart:4601:5)
#3 Element.inflateWidget (package:flutter/src/widgets/framework.dart:3569:14)
#4 Element.updateChild (package:flutter/src/widgets/framework.dart:3324:20)

What should i do ?

I'm having the same problem, even with a new project:
#1 create a new flutter project
#2 update pubscec.yaml dependencies => splashscreen: ^1.3.3
#3 copy the example from the first page into main.dart:
`import 'package:flutter/material.dart';
import 'package:splashscreen/splashscreen.dart';

void main() {
runApp(new MaterialApp(
home: new MyApp(),
));
}

class MyApp extends StatefulWidget {
@OverRide
_MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State {
@OverRide
Widget build(BuildContext context) {
return new SplashScreen(
seconds: 14,
navigateAfterSeconds: new AfterSplash(),
title: new Text(
'Welcome In SplashScreen',
style: new TextStyle(fontWeight: FontWeight.bold, fontSize: 20.0),
),
image: new Image.network('https://i.imgur.com/TyCSG9A.png'),
backgroundColor: Colors.white,
styleTextUnderTheLoader: new TextStyle(),
photoSize: 100.0,
onClick: () => print("Flutter Egypt"),
loaderColor: Colors.red);
}
}

class AfterSplash extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text("Welcome In SplashScreen Package"),
automaticallyImplyLeading: false),
body: new Center(
child: new Text(
"Done!",
style: new TextStyle(fontWeight: FontWeight.bold, fontSize: 30.0),
),
),
);
}
}

Thanks for this report, I will check it and push a new version soon.

The if statement at line 83 should probably look something like this

if (widget.routeName != null && widget.routeName is String && "${widget.routeName[0]}" != "/") throw new ArgumentError("widget.routeName must be a String beginning with forward slash (/)");
