Answer 1

Wrapping your search button with this will reduce the padding.

Not sure how much of the padding you wanted to remove.

SizedBox(
  width: 10.0,
  child: IconButton(
    padding: EdgeInsets.zero,
    icon: Icon(Icons.search),
    onPressed: () {},
  ),
),

Answer 2

Add this lines to remove default padding of IconButton:

IconButton(
     constraints: BoxConstraints(),
     padding: const EdgeInsets.all(0),),

Answer 3

Try like this

appBar: AppBar(
      title: Text(title),
      backgroundColor: kPrimaryLightColor,
      actions: <Widget>[
        Padding(
            padding: EdgeInsets.only(right: 20.0),
            child: GestureDetector(
              onTap: () {},
              child: Icon(
                Icons.message_rounded,
                size: 30.0,
              ),
            )),

Solution 1

Just add a property called "titleSpacing" in your AppBar Tag,

Sample

appBar: AppBar(
        titleSpacing: 0,     //Add this line to your code
        title: Text(widget.title),
        leading: Icon(Icons.android),
        ),

Solution 2

Or wrap your title with "Transform.translate" and Add property "offset".

sample

title: Transform.translate(
       offset: Offset(-30.0, 0.0),
       child: Text('your app title')
       ),
