Working with Flutter it is a pleasant experience. Easy, fast, productive, it just works.

We can create Flutter Apps for iOS and Android in an extremly short time. But even more, we can deliver a web based experience to the users. not just mobile “native”.

Goolge says Flutter web it is not ready for production . I believe so, there are still some missing features when it comes to making your App ready for the web.

But that does not mean that we can just use it and be aware of the little limitations we still have.

I have been working on a web based project with Flutter. The first issue I found is that the user does not have the same experience as on the web.

The issue

One thing you just notice straight away is that the mouse is not like in the standard web when hovering on clickable elements Flutter web cursor with hand pointer style .

It does not change to a little hand Flutter web cursor with hand pointer style to let you know you can click on it.

Flutter web cursor with hand pointer style

Well, I wanted to deliver a web site! not a weird web!

The Solution

Modify the index.html giving an Id to the container.

<body id="flutter_container">

In your dart file:

Wrap your “clickable” widget into this MouseCursor widget that looks like this:

class MouseCursor extends MouseRegion{

  static var clickableArea = document.getElementById("flutter_container"); //your element id

  MouseCursor({@required Widget child}):super(
      child:child,
      onHover: _mouseOnHover,
       onExit: _mouseOnExit);

  static void _mouseOnHover(PointerHoverEvent event) {
      clickableArea.style.cursor = "pointer";
  }


  static void _mouseOnExit(PointerExitEvent event) {
    clickableArea.style.cursor = "default";
  }
}

So you should use it this way:
