inappview with uni_links

[no1-knows]

Hello! I'm newbie for smartphone app. I would like to open the webpage at inappview which is as same as universal links url on mail app.

It's kind of like below. If I got mail with authentication links like "http://example.com/sign_in/wtCpS0ObF-UMjvzev" and I tap it, then I would like to open my app and show the above page. But my app doesn't change the page.

What is done

• Universal links setting seems to be done. I can open app when i tap url.
• StreamBuilder code seems to be done. I checked url at // return Text(url);

Any information would greatly help.

This sample code works with uni_links!!

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