title: How to disable splash highlight of FlatButton in Flutter?
body: <p>I have a FlatButton. I don't want the splash highlight when the button is clicked. I tried changing the splash colour to transparent, but that didn't work. Here is the code for my FlatButton.</p>
  
  <pre><code>Widget button = new Container(
    child: new Container(
      padding: new EdgeInsets.only(bottom: 20.0),
      alignment: Alignment.center,
      child: new FlatButton(
        onPressed: () {
          _onClickSignInButton();
        },
        splashColor: Colors.transparent,
        child: new Stack(
          alignment: Alignment.center,
          children: &lt;Widget&gt;[
            new Image.asset('images/1.0x/button1.png',
            ),
            new Text("SIGN IN",
              style: new TextStyle(
                  color: Colors.white,
                  fontWeight: FontWeight.bold,
                  fontSize: 16.0
                ),
            )
          ],
        ),
      ),
    ),
  );
  </code></pre>
