Flutter: Widgets in Row are not aligned

I use row widget with two widgets inside, a text widget and iconbutton but iconbutton is not aligned with text and I don't know how to do it. This is a screenshot to show you
Row(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: widgets[index],
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {
setState(() {
widgets.remove(widgets[index]);
}),
})
],
),

Use mainAxisSize: MainAxisSize.min,
Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.grey, width: 1),
borderRadius: BorderRadius.all(Radius.circular(8.0))),
child: Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: Text(
'Theo',
style:
TextStyle(color: Colors.deepOrangeAccent, fontSize: 20),
),
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {})
],
),
),
Output:

replace CrossAxisAlignment.start with CrossAxisAlignment.baseline and add textBaseline: TextBaseline.alphabetic like this:
Row(
mainAxisSize: MainAxisSize.min,
textBaseline: TextBaseline.alphabetic,
crossAxisAlignment: CrossAxisAlignment.baseline,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: widgets[index],
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {
setState(() {
widgets.remove(widgets[index]);
}),
})
],
),
You may need this to confirm:

I used InkWell instead of iconbutton and it works

);
}
Expected:
Getting

You could do this with timeline_tile.
Also, the beautiful_timelines repository contains some examples built with this package.
Web demo

You need to set crossAxisAligment for rows:
Widget timelineRow(String title, String subTile) {
return Row(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start, # <- this

I'm getting this
and I'm trying to achieve this
and this

You just need to add the following line in your code :
crossAxisAlignment: CrossAxisAlignment.start
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,

There is a property name cross-axis alignment for both Row and Column
As I see you have used main axis alignment.
Main Axis for Column is to align children Vertically.
Main Axis for Row is to align children Horizontally.
Cross Axis for Column is to align children Horizontally.
Cross Axis for Row is to align children Vertically.
So you can try with this for your row
crossAxisAlignment: CrossAxisAlignment.start,

Flutter | How to make custom button of BottomNavigationBar in flutter?

I want make a button with text and icon inside it, with custom background color and custom width. with fix position (not scrollable). would you like to help me please ?
here are the code:
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.shifting,
currentIndex: 0, // this will be set when a new tab is tapped
items: [
BottomNavigationBarItem(icon: Icon(Icons.supervised_user_circle), title: Text('Players'),backgroundColor: Colors.red),
BottomNavigationBarItem(icon: Icon(Icons.whatshot), title: Text('Trending'),backgroundColor: Colors.blueAccent),
BottomNavigationBarItem(icon: Icon(Icons.access_time), title: Text('Highlights'),backgroundColor: Colors.yellow)
]
its only give a color for the icon.
this is what I want:

Here you go
Widget build(context) {
return Scaffold(
bottomNavigationBar: Container(
height: 56,
margin: EdgeInsets.symmetric(vertical: 24, horizontal: 12),
child: Row(
children: <Widget>[
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.chat, color: Colors.white), Text("CHAT", style: TextStyle(color: Colors.white))],
),
),
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.notifications_active, color: Colors.white), Text("NOTIF", style: TextStyle(color: Colors.white))],
),
),
Expanded(
child: Container(
alignment: Alignment.center,
color: Colors.red,
child: Text("BUY NOW", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 18)),
),
),
],
),
),
);
}

You may want to look at the concept of a BottomAppBar instead.
This bar accepts any widget as children not just BottomNavigationBarItems.
You could try this:
BottomAppBar(
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Expanded(
child: SizedBox(
height: 44,
child: Material(
type: MaterialType.transparency,
child: InkWell(
onTap: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.add, color: Colors.blue, size: 24),
Text("Add")
],
),
),
),
),
),
]
),
)
