responsive_ui package helps you to create a responsive widget and Nested responsive widget too. Works on all flutter platform (android, iOs ,web ) with both Portrait and LandScape mode. #
sample video #
Getting Started #
It works as same as Bootstrap Row Column method, Splitting screen into 12 columns and placing widget by combining column based on screen size.
Screens #
For mobiles ( screen size <= 600px wide ) #
For tablets ( screen size > 600px wide && <= 990 px wide ) #
For laptops ( screen size > 990px wide ) #
Widgets #
The Responsive UI Package contains two simple widgets.
- Responsive()
- ResponsiveChild()
(s = small, m = medium, l = large)
1. Responsive() #
Responsive intakes List<ResponsiveChild> with default column/screen size for each widget can be declared.
Responsive(
defaultColS : 12,//default column size for Small screen 12
defaultColM : 6, //default column size for Medium screen 12
defaultColL : 4, //default column size for Large screen 12
children:<Widget>[
ResponsiveChild(
child:Container(
color: Colors.amber,
alignment: Alignment.center,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text('child 1'),
),
),
),
ResponsiveChild(
child:Container(
color: Colors.blue,
alignment: Alignment.center,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text('child 2'),
),
),
),
]
)
defaultColS, defaultColM, defaultColL default to 12 & various from [0-12]
0 - 0.0 width (gone)
12 - full width (provided by parent widget not screen width)
2. ResponsiveChild() #
To Override the defaultCol size use ResponsiveChild() col value.
ResponsiveChild() intakes child & column sizes.
Offset #
To offset, simply add offsetS /offsetM /offsetL to the ResponsiveChild() widget with respective size.
Lite Example #
Responsive(
defaultColS : 12, //defaults to 12
defaultColM : 6, //defaults to 12
defaultColL : 4, //defaults to 12
children:<Widget>[
ResponsiveChild(
colS: 10, // colS & ColL override the defaultCol size
colL: 3,
offsetS :2 // added offset
child: Container(
color: Colors.amber,
alignment: Alignment.center,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text('child 1'),
),
),
),
ResponsiveChild( // as colM not mentioned, it takes the defaulColM size
colS: 10,
colL: 3,
child: Container(
alignment: Alignment.center,
color: Colors.redAccent,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text('Column Child'),
),
),
),
]
)
ResponsiveChild() works only as direct child of Responsive() widget #
Nested Responsive #
Placing a Responsive() widget into a Responsive().
The child Responsive() widget takes a width provided by Parent Responsive() widget and not the screen width

@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey[350],
