Running the code given as example:

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

class MyInAppBrowser extends InAppBrowser {

  @override
  Future onLoadStart(String url) async {
    print("\n\nStarted $url\n\n");
  }

  @override
  Future onLoadStop(String url) async {
    print("\n\nStopped $url\n\n");
  }

  @override
  void onLoadError(String url, int code, String message) {
    print("\n\nCan't load $url.. Error: $message\n\n");
  }

  @override
  void onExit() {
    print("\n\nBrowser closed!\n\n");
  }

}

MyInAppBrowser inAppBrowserFallback = new MyInAppBrowser();

class MyChromeSafariBrowser extends ChromeSafariBrowser {

  MyChromeSafariBrowser(browserFallback) : super(browserFallback);

  @override
  void onOpened() {
    print("ChromeSafari browser opened");
  }

  @override
  void onLoaded() {
    print("ChromeSafari browser loaded");
  }

  @override
  void onClosed() {
    print("ChromeSafari browser closed");
  }
}

MyChromeSafariBrowser chromeSafariBrowser = new MyChromeSafariBrowser(inAppBrowserFallback);

void main() => runApp(new MyApp());

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

class _MyAppState extends State<MyApp> {

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

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('Flutter InAppBrowser Plugin example app'),
        ),
        body: new Center(
          child: new RaisedButton(onPressed: () {
            chromeSafariBrowser.open("https://flutter.io/", options: {
                  "addShareButton": false,
                  "toolbarBackgroundColor": "#000000",
                  "dismissButtonStyle": 1,
                  "preferredBarTintColor": "#000000",
                },
              optionsFallback: {
                "toolbarTopBackgroundColor": "#000000",
                "closeButtonCaption": "Close"
              });
          },
          child: Text("Open ChromeSafariBrowser")
          ),
        ),
      ),
    );
  }
}

I can run the application, but when i try to click the button that have to open ChromeSafariBrowser, it fails.

Console is returning this:
