Answer 1

This Should Solve this :
ExpansionTile(
title: Text('Item0'),
children: <Widget>[
Padding(
padding: const EdgeInsets.symmetric(horizontal: 16.0),
child: Align(
alignment: Alignment.topLeft,
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('subHeading1'),
Text('subHeading2')
],
),
),
),
],
),

Answer 2

You can have the padding and the alignment with a container:
ExpansionTile(
title: Text('Item0'),
children: <Widget>[
Container(
padding: const EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.topLeft,
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('subHeading1'),
Text('subHeading2')
],
),
),
],
),
