Spacing Icons in a container in Flutter

Issue

I am trying to find a better alternative to spacing my icons in Flutter, I am currently using the SizedBox(...) Widget. Although I am not sure if this is the best method to use, the sized box seems to mess up the spacing of other icons when I am adjusting the height/width. Are there any alternatives to spacing your icons inside a container. I added a picture of the UI to the post, the icons are in the menu on the left side. Login Screen Image

Widget build(BuildContext context) {
    return Container(

        height: 800,

                        ),

Solution

You can put all the icons in a Column widget. The column widget has a parameter MainAxisAlignment, you can set this parameter to spaceEvenly.

See https://api.flutter.dev/flutter/widgets/Column-class.html for the Column widget

and see https://api.flutter.dev/flutter/rendering/MainAxisAlignment.html for the MainAxisAlignment

Put the Column widget inside a Container widget.

Container(
    child: Column(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly
        children: [
            Icon()
            Icon()
        ],
    ),
),
