You are not returning the right value to the shouldOverrideUrlLoading event. As it is written in the API docs, you should return a ShouldOverrideUrlLoadingAction.

For example, using your example, you can simply return ShouldOverrideUrlLoadingAction.ALLOW; (I don't know, it depends on your use case):

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

Future main() async {
  runApp(new MyApp());
}

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

class _MyAppState extends State<MyApp> {
  InAppWebViewController webView;
  String url = "";
  double progress = 0;

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

  @override
  void dispose() {
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Container(
            child: Column(children: <Widget>[
              Expanded(
                child: Container(
                  child: InAppWebView(
                    initialUrl: "https://www.onestare.com/",
                    shouldOverrideUrlLoading:
                        (InAppWebViewController controller,
                            ShouldOverrideUrlLoadingRequest
                                shouldOverrideUrlLoadingRequest) {
                      print("****"+shouldOverrideUrlLoadingRequest.url);
											 
                      _launchURL(shouldOverrideUrlLoadingRequest.url);
		     return ShouldOverrideUrlLoadingAction.ALLOW;
                    },
                    initialOptions: InAppWebViewGroupOptions(
                      crossPlatform: InAppWebViewOptions(
                        useShouldOverrideUrlLoading: true,
                        debuggingEnabled: true,
                      ),
                    ),
                    onWebViewCreated: (InAppWebViewController controller) {
                      webView = controller;
                    },
                    onLoadStart:
                        (InAppWebViewController controller, String url) {},
                    onLoadStop:
                        (InAppWebViewController controller, String url) {},
                  ),
                ),
              ),
            ]),
          ),
        ),
      ),
    );
  }
}

_launchURL(String url) async {
  if (await canLaunch(url)) {
    await launch(url);
  } else {
    throw 'Could not launch $url';
  }
}
