'initState' is inherited as a getter (from 'State') and also a method (from 'AfterLayoutMixin').

import 'package:flutter/material.dart';
import 'package:after_layout/after_layout.dart';

class IntroPage extends StatefulWidget {
  @override
  _IntroPageState createState() => _IntroPageState();
}

class _IntroPageState extends State<IntroPage> with AfterLayoutMixin<IntroPage> {
  BuildContext ctx;
  
@override
  Widget build(BuildContext context) {
    ctx = context;
    return new Scaffold(body: new Container(color: Colors.red));
  }

   @override
  void afterFirstLayout(BuildContext context) {
    // Calling the same function "after layout" to resolve the issue.
    firstRun();
  }

  Future<Null> firstRun() async {
     print("first run");
    
  }
}

please healp! I keep getting 'initState' is inherited as a getter (from 'State') and also a method (from 'AfterLayoutMixin').
thats my page code above.

If you check the code from AfterLayoutMixin you see that this pub is already overriding your initState method:

mixin AfterLayoutMixin<T extends StatefulWidget> on State<T> {
  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => afterFirstLayout(context));
  }

  void afterFirstLayout(BuildContext context);
}

You can't override the same method again. Think of after_layout as a substitute with a slightly different trigger.
