For those who want to have the click effect similar to InkWell widget and with border radius option:

Add to your pubspec.yaml file

dependencies:
  universal_html: ^1.1.4

Then add to the index.html file the following the tag as below:

Finally create the following widget and use encapsulated all the necessary widgets:

import 'package:flutter/foundation.dart';
import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';
import 'package:universal_html/prefer_sdk/html.dart' as html;

class InkWellMouseRegion extends InkWell {
  InkWellMouseRegion({
    Key key,
    @required Widget child,
    @required GestureTapCallback onTap,
    double borderRadius = 0,
  }) : super(
          key: key,
          child: !kIsWeb ? child : HoverAware(child: child),
          onTap: onTap,
          borderRadius: BorderRadius.circular(borderRadius),
        );
}

class HoverAware extends MouseRegion {

  // get a reference to the body element that we previously altered 
  static final appContainer = html.window.document.getElementById('app-container');

  HoverAware({Widget child}) : super(
    onHover: (PointerHoverEvent evt) {
      appContainer.style.cursor='pointer';
      // you can use any of these: 
      // 'help', 'wait', 'move', 'crosshair', 'text' or 'pointer'
      // more options/details here: http://www.javascripter.net/faq/stylesc.htm
    },
    onExit: (PointerExitEvent evt) {
      // set cursor's style 'default' to return it to the original state
      appContainer.style.cursor='default';
    },
    child: child
  );

}
