Environment

Technology	Version
Flutter version	2.15.0
Plugin version	5.3.2
Android version	12
iOS version	15.2
Xcode version	13.2.1

Device information: Android Emulator Pixel 3a and iPhone 13 Simulator

Description

When no initialRequestUrl is provided to an inAppWebView or a HeadlessInAppWebView a callback to onLoadStop is triggered with an Uri for about:blank.

Expected behavior: When initialRequestUrl is null it should not trigger a callback to onLoadStop, since no url has been set.

Current behavior: A callback to onLoadStop is being triggered.

Steps to reproduce

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

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String msg = "";

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: SafeArea(
        child: Scaffold(
          body: Column(
            children: [
              Padding(
                padding: const EdgeInsets.all(16),
                child: Text(msg),
              ),
              Expanded(
                child: InAppWebView(
                  onLoadStop: (controller, url) {
                    setState(() => msg = "onLoad: $url");
                  },
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!
