Pub

Getting Started

Live demo : https://bharathraj-e.github.io/responsive_ui/ Have a look!

It works as same as Bootstrap / Materialize Row Column method, Splitting screen into 12 columns and placing widget by combining column based on screen size.

    Responsive(
        children: <Widget>[
            Div(
                division:Division(
                    colS: 5,
                    offsetL: 2,
                ),
                child: Card(child: Icon(Icons.game))
            ),
            Div(
                division:Division(
                    colS: 12,
                    colM: 6,
                    colL: 4,
                ),  
                child: Text('responsive ui')
            )          
        ]
    )

Widgets

The Responsive UI Package contains two simple widgets.

1. Div()
2. Responsive()

1. Div()

Arguments	inputs	if null / default to
child	Widget	required
division	Division	if null defaluts to Division()

Divison() intakes column sizes and offSets.

Arguments	inputs	if null / default to
colXS	(int) 0-12	12
colS	(int) 0-12	colXS value
colM	(int) 0-12	ColS value
colL	(int) 0-12	ColM value
colXL	(int) 0-12	ColL value
offsetXS	(int) 0-12	0
offsetS	(int) 0-12	0
offsetM	(int) 0-12	0
offsetL	(int) 0-12	0
offsetXL	(int) 0-12	0

(XS = Extra Small, S = small, M = medium, L = large, XL = Extra Large)

• 0 - 0.0 width (gone) (replaced with SizedBox.shrink())

• 12 - full width (provided by parent widget not screen width)

• Parent widget should not be a horizontal scroll type widget

• To offset, simply add offsetS / offsetM / offsetL to the Div() widget with colS / colM / colL respectively.

• Offset works for their respective column sizes.

2. Responsive()

Responsive intakes List<Widget> or List<Div> with default column/screen size for each widget can be declared.

Arguments	inputs	if null / default
children	List / List	not null / required / empty[]
alignment	WrapAlignment	WrapAlignment.start
runAlignment	WrapAlignment	WrapAlignment.start
crossAxisAlignment	WrapCrossAlignment	WrapCrossAlignment.start
runSpacing	double	0.0

Note

• Responsive widget is a Wrap widget.

• Responsive & Div() widget need Finite width to work.

• Div() works with vertical scroll not in horizontal scroll, as it calculations are base on width only.

• Div() works as expected when it placed as a direct child of Responsive() widget's children.

• Sum of the offset and the respective col should be <= to 12

Nested Responsive

Place a Responsive() widget into a Div().

The nested Responsive() widget takes the width provided by parent Div() widget and not the screen width

sample

Screen Types

Type	Default Size
Xtra small	< 375.0
Small	375.0 - 596.0
Medium	596.0 - 897.0
Large	897.0 - 1232.0
Xtra Large	>1232.0

Override / Set your default size

Yes, now you can set your own breakpoints, that applies to all the Responsive & Div widgets.

void main() {
  // sample 1
  Responsive.setGlobalBreakPoints(400.0, 600.0, 997.0, 1380.0);
  // Sample 2 
  Responsive.setGlobalBreakPoints(0, 596.0, 897.0, 1232.0);
  // Since the first value is 0 : colXS is always neglected
  runApp(const MyApp());
}

responsive_ui is made simply using Wrap() and LayoutBuilder() with a bits of logics.
