问题

以下是您要翻译的代码部分:

So I'am making just a hangman game app on flutter and I wanted to add a splash screen to it with an image. I'am sure I have the correct identation in the pub spec.yaml,also the correct path and I don't know why it keeps getting me error. Can you help me please?

Her is my splash screen code:

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:splashscreen/splashscreen.dart';
import '../../main.dart';
import 'package:hangman/utilities/constants.dart';

class LoadingScreen extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return _LoadingScreen();
  }
}

class _LoadingScreen extends State<LoadingScreen> {
  CustomColors colors = CustomColors();

  @override
  void initState() {
    super.initState();
    //loading();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: SplashScreen(
          loaderColor: colors.secondColor,
          seconds: 1000,
          navigateAfterSeconds: const MyHomePage(title: 'HANGMAN'),
          backgroundColor: colors.mainColor,
          title: Text(
            'HANGMAN',
            style: TextStyle(
                fontWeight: FontWeight.bold,
                fontSize: 50.0,
                color: colors.secondColor),
          ),
          image: const Image(image: AssetImage('assets/images/hangmanLoading.png'),),
          photoSize: 150.0,
        ));
  }
}
Here is my pubspec.yaml:

Just remove the "/" from the end of this line in the pubspec.yaml

  • assets/images/hangmanLoading.png/
