A flutter library to add SizedBox between children in list of widgets

A flutter library to insert SizedBox between every children widget in Column, Row, and any List of widgets.

Getting started

Visit this library in pub.dev

#Add dependency

dependencies:  
 spacious_widgets: ^1.1.0+3

Features

• Single extension function to add SizedBox between every widgets in a List
• Adjust any single inserted SizedBox
• Ignore SizedBox anywhere
• Doesn't insert SizedBox around Spacer widget

Usage

List<Widget> setSpace({double? start, double? height, double? width, double? end});  

Normally to add space between widgets we use SizedBox between every widget.

Column(  
   children: [
      Text("A"),
      SizedBox(height: 10),
      Text("B"),
      SizedBox(height: 10),
      Text("C"),
      SizedBox(height: 10),
      Text("D"),
      SizedBox(height: 10),
      Text("E"),
   ],
)  

This is tedious when the List gets bigger. For any n widgets, we have to put n-1 SizedBox, and if we need space at the start and end we need n+1 SizedBox

So with this library the SizedBox is added automatically, so the actual List is not cluttered with SizedBox.

Column(  
   children: [
      Text("A"),
      Text("B"),
      Text("C"),
      Text("D"),
      Text("E"),
   ].setSpace(height: 10),
)  

The above inserts SizedBox(height: 10, width: null) between every widget.

For Row use setSpace(width: 10) which inserts SizedBox(width: 10, height: null).

start inserts SizedBox before the first widget, end inserts SizedBox after the last widget

[  
   ...widgets
].setSpace(start: 15, height: 10, end: 15),  

The start and end parameter requires height or width parameter to be set.
start and end overrides the height or width value. To only insert SizedBox at the start and end, set height or width to 0

Adjustments

To adjust the height or width in the inserted SizedBox, use the widgets AdjustSpace and NoSpace

Column(  
    children: [
        Text("A"),
        AdjustSpace(adjust: 10),   // increase 10 in the height
        Text("B"),
        AdjustSpace(adjust: -5),   // decrease 5 in the height
        Text("C"),  
        AdjustSpace(override: 20), // override the height
        Text("D"),
        NoSpace(),                 // don't insert SizedBox here
        Text("E"),
        Text("F"),
    ].setSpace(start: 15, height: 10, end: 15),
)
