If the purple area is inside an Expanded widget, how would I go about to position the button? I've implemented that UI by setting a fixed height to the purple container but haven't been able to understand how to achieve the same effect if the height is variable, depending on the content.
I was able to get close by using Stack and Positioned widgets but then the button is not really clickable. If anyone can give me a general idea on how to achieve the desired goal I would be thankful.
Here's my attempt (demo case)
@override
Widget build(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 1,
child: SingleChildScrollView(
child: Column(
children: <Widget>[
Container(
decoration: BoxDecoration(
color: Colors.redAccent,
),
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Stack(
children: <Widget> [
Padding(
padding: const EdgeInsets.only(bottom: 40.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Icon(
Icons.book,
color: Colors.white,
size: 40.0
),
Container(
width: 90.0,
child: new Divider(color: Colors.white),
),
Text(
"Some random text -",
style: TextStyle(color: Colors.white, fontSize: 25.0),
),
Padding(
padding: const EdgeInsets.only(top: 8.0, right: 70.0),
child: Row(
children: <Widget>[
Flexible(
child: Text(
'More random text that can vary a lot!',
style: TextStyle(
color: Colors.white,
fontSize: 16.0,
fontWeight: FontWeight.bold,
),
),
),
],
),
),
Padding(
padding: const EdgeInsets.only(top: 8.0),
child: Row(
children: <Widget>[
Text(
'Random text ',
style: TextStyle(

fontSize: 16.0,
fontWeight: FontWeight.bold,
),
),
],
),
),
Padding(

child: Row(
children: <Widget>[
Text(
'Random',
style: TextStyle(

),
),
],
),
),
],
),
),
Positioned(
bottom: 0.0,
left: MediaQuery.of(context).size.width - 100.0,
child: FractionalTranslation(
translation: const Offset(0.0, 0.8),
child: FloatingActionButton(
backgroundColor: Colors.white,
foregroundColor: Colors.redAccent,
child: new Icon(
Icons.map
),
onPressed: () {
},
),
),
),
]
),
),
),
Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(top: 8.0, left: 8.0),
child: Row(
children: <Widget>[
Flexible(
child: Text(
"Random text",
style: new TextStyle(
fontFamily: 'Raleway',
fontSize: 16.0,
color: Colors.black38
)
),
),
],
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Text(
"Random text - long text",
style: new TextStyle(
fontFamily: 'Raleway',
fontSize: 18.0
)
),
),
],
)
],
)
),
),
],
);
