How to make buttons closer?

Question

Dart

It is necessary to reduce the distance between the buttons, I want to make them a little tighter to each other.

Expanded(
                      child: Align(
                        alignment: Alignment.bottomLeft,
                        child: Column(
                          mainAxisAlignment: MainAxisAlignment.end,
                          children: <Widget>[
                            Padding(padding: EdgeInsets.fromLTRB(10, 0, 0, 0),
                              child: Row(
                                children: [
                                  TextButton(onPressed: () => launch('tel://111'),
                                      child: Row(
                                        children: [
                                          Icon(Icons.phone_iphone_outlined, color: Colors.white, size: 20),
                                          Padding(padding: EdgeInsets.only(left: 7.0),),

Answer 1

I think so, there may still be something in the properties

TextButton(
     style: TextButton.styleFrom(
           padding: /// тут,

Answer 2

This is where the indents are edited
Padding(padding: EdgeInsets.fromLTRB(...),
