Padding and layout of card in flutter - flutter

Question

I am trying to add padding to the text in the card and for some reason, it is not working.
This is my code:
Widget build(BuildContext context) {
return Scaffold(
body: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
new Container(
height: 170.0,
child: Card(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
ListTile(
leading: Icon(Icons.phone),
title: Align(
child: Text('Need immediate help'),
alignment: Alignment(-1.2, 1.0),
),
subtitle: Column(
children: <Widget>[
Align(
child: Text('In an emergency, call 999.'),
alignment: Alignment(-1.2, 0),
),
Align(
child: Text(
"If you're in crisis and need to speak to someone call NHS 111."),
alignment: Alignment(-1.2, 0),
),
],
),
),
ButtonBar(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
ButtonTheme(
minWidth: 150.0,
child: RaisedButton(
padding: EdgeInsets.all(8.0),
child: const Text('999'),
onPressed: () => launch("tel://000"),
),
),
ButtonTheme(
minWidth: 150.0,
child: RaisedButton(
padding: EdgeInsets.all(8.0),
child: const Text('111'),
onPressed: () => launch("tel://000"),
),
Currently it looks like this:
I am wanting to add padding around the text so it looks better but using alignment isn't affecting the second subtitle and isn't affecting the padding above or below any of the text. Any help would be appreciated!

Answer 1

Change mainAxisAlignment property of your Column as following and remove the mainAxisSize property
Column(
mainAxisAlignment: MainAxisAlignment.center,
// ...
),
Edit
Adjust your subtitle like this
ListTile(
leading: Icon(Icons.phone),
title: Align(
child: Text('Need immediate help'),
alignment: Alignment(-1.2, 1.0),
),
subtitle: Align(
alignment: Alignment(- 65.0, 1.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text('In an emergency, call 999.', textAlign: TextAlign.left,),
Text("If you're in crisis and need to speak to someone call NHS 111.", textAlign: TextAlign.left,),
],
),
),
),
