Bring responsive widgets to flutter! this package has some widgets to make a simple responsive ui

Getting Started

first, add responsively to your pubspec dependencies.

To import responsively:

import 'package:responsively/responsively.dart';

ResponsiveRow

Responsive grid look like bootstrap grid, support width, offset and order for diffrent BreakPoints

ResponsiveRow(
 totalColumn = 12, // you can change total columns as you want
  mainAxisSpacing = 0, // horizontal column spacing
  crossAxisSpacing = 0, //vertical column spacing,
  mainAxisAlignment = MainAxisResponsiveRowAlignment.start, // horizontal alignment of columns
  crossAxisAlignment = CrossAxisResponsiveRowAlignment.start, // vertical alignment of columns
  @required children, // your grid columns
);

examples :

1. simple grid :

ResponsiveRow(
  children: [
    ResponsiveColumn(
      width: ColumnWidth(
        lgUp: 3, // fill 3 from totalColumn column in large screen and bigger
        mdUp: 4, // fill 4 from totalColumn column in medium screen and bigger
        smUp: 6, // fill 6 from totalColumn column in small screen and bigger
        defaultValue: 12, // if device size not exist in your definition defaultValue is your column width
      ),
      child: Container(
        height: 100,
        color: Colors.purple,
      )
    ),
    ResponsiveColumn(
      width: ColumnWidth(
        mdUp: 4, // just in medium screen and bigger fill 4 from totalColumn column, otherwise because defaultValue not defined fill totalColumn from totalColumn column in other screen sizes
      ),
      child: Container(
        height: 100,
        color: Colors.deepOrange,
      )
    ),
  ],
),

note : ColumnWidth has many properties, all properties is optional, if there is no any value, defaultValue used, if defaultValue not defined, it's totalColumn.

list ColumnWidth properties :

ColumnWidth(
  int xs, // just in extra small size
  int xsUp, // extra small size and bigger
  int sm, // just in small size
  int smUp, // small size and bigger
  int smDown, // small size and smaller
  int md, // just in medium size
  int mdUp, // medium size and bigger
  int mdDown, // medium size and smaller
  int lg, // just in large size
  int lgUp, // large size and bigger
  int lgDown, // large size and smaller
  int xl, // just in extra large size
  int defaultValue, // fallback value
),

2. grid combine order and offset feature :

ResponsiveRow(
  children: [
    ResponsiveColumn(
      width: ColumnWidth(
        lgUp: 3, // fill 3 from totalColumn column in large screen and bigger
        mdUp: 4, // fill 4 from totalColumn column in medium screen and bigger
        smUp: 6, // fill 6 from totalColumn column in small screen and bigger
        defaultValue: 12, // if device size not exist in your definition defaultValue is your column width
      ),
      order: ColumnOrder(
        lgUp: 0,
        mdUp: 1,
        smUp: 0,
        xsUp: 1,
      ),
      offset: ColumnOffset(
        lgUp: 2,
      ),
      child: Container(
        height: 100,
        color: Colors.purple,
      )
    ),
    ResponsiveColumn(
      width: ColumnWidth(
        lgUp: 3, // fill 3 from totalColumn column in large screen and bigger
        mdUp: 4, // fill 4 from totalColumn column in medium screen and bigger
        smUp: 6, // fill 6 from totalColumn column in small screen and bigger
      ),
      order: ColumnOrder(
        lgUp: 1,
        mdUp: 0,
        smUp: 1,
        xsUp: 0,
      ),
      offset: ColumnOffset(
        mdUp: 1,
      ),
      child: Container(
        height: 100,
        color: Colors.deepOrange,
      )
    ),
  ],
),

note : ColumnOrder has many properties, all properties is optional, if there is no any value, defaultValue used, if defaultValue not defined, it's null ( computed by index )

list ColumnOrder properties :

ColumnOrder(
  int xs, // just in extra small size
  int xsUp, // extra small size and bigger
  int sm, // just in small size
  int smUp, // small size and bigger
  int smDown, // small size and smaller
  int md, // just in medium size
  int mdUp, // medium size and bigger
  int mdDown, // medium size and smaller
  int lg, // just in large size
  int lgUp, // large size and bigger
  int lgDown, // large size and smaller
  int xl, // just in extra large size
  int defaultValue, // fallback value
),

ColumnOffset has many properties, all properties is optional, if there is no any value, defaultValue used, if defaultValue not defined, it's 0

list ColumnOrder properties :

ColumnOffset(
  int xs, // just in extra small size
  int xsUp, // extra small size and bigger
  int sm, // just in small size
  int smUp, // small size and bigger
  int smDown, // small size and smaller
  int md, // just in medium size
  int mdUp, // medium size and bigger
  int mdDown, // medium size and smaller
  int lg, // just in large size
  int lgUp, // large size and bigger
  int lgDown, // large size and smaller
  int xl, // just in extra large size
  int defaultValue, // fallback value
),

ResponsiveWidget

this widget give value by current BreakPoint

ResponsiveWidget<T>(
  ResponsiveWidgetBuilder<T> builder,
  ResponsiveInfo<T> value,
);

ResponsiveWidgetBuilder<T> = Widget Function(BuildContext context, T value);

ResponsiveInfo<T>(
  T xs, // just in extra small size
  T xsUp, // extra small size and bigger
  T sm, // just in small size
  T smUp, // small size and bigger
  T smDown, // small size and smaller
  T md, // just in medium size
  T mdUp, // medium size and bigger
  T mdDown, // medium size and smaller
  T lg, // just in large size
  T lgUp, // large size and bigger
  T lgDown, // large size and smaller
  T xl, // just in extra large size
  T defaultValue, // fallback value
),

examples :

1. in this example when screen size is lgUp color is Colors.purple, when screen size is mdUp color is Colors.deepOrange otherwise color is Colors.black

ResponsiveWidget<Color>(
  value: ResponsiveInfo(
    lgUp: Colors.purple,
    mdUp: Colors.deepOrange,
    defaultValue: Colors.black,
  ),
  builder: (context, color) {
    return Container(
      height: 100,
      color: color,
    );
  },
)

2. in this example when screen size is mdUp textAlign is TextAlign.right otherwise TextAlign.left

ResponsiveWidget<TextAlign>(
  value: ResponsiveInfo(
    mdUp: TextAlign.right,
    defaultValue: TextAlign.left,
  ),
  builder: (context, textAlign) {
    return Text(
      "SAMPLE",
      textAlign: textAlign,
    );
  },
)

ResponsiveBuilder

this widget give current BP and you can build your UI by current BreakPoint

ResponsiveBuilder(
  BreakPointBuilder builder,
);

BreakPointBuilder = Widget Function(BuildContext context, BP breakPoint);

example :

ResponsiveBuilder(
  builder: (context, bp) {
    if(bp == BP.lg) {
      return Text('YOUR ARE IN LG BREAKPOINT');
    }
    return SizedBox();
  },
),

ResponsiveSizedBox

responsive SizedBox, width of SizedBox get by current BreakPoint

ResponsiveSizedBox(
  ResponsiveWidth width,
  double height,
  Widget child,
);

ResponsiveWidth(
  int xs, // just in extra small size
  int xsUp, // extra small size and bigger
  int sm, // just in small size
  int smUp, // small size and bigger
  int smDown, // small size and smaller
  int md, // just in medium size
  int mdUp, // medium size and bigger
  int mdDown, // medium size and smaller
  int lg, // just in large size
  int lgUp, // large size and bigger
  int lgDown, // large size and smaller
  int xl, // just in extra large size
  int defaultValue, // fallback value
),

example :

in this example if screen size is lgUp, width is 50.0, if screen size is mdUp width is 40.0 otherwise 30.0

ResponsiveSizedBox(
  width: ResponsiveWidth(
    lgUp: 50.0,
    mdUp: 40.0,
    defaultValue: 30.0
  ),
  child: Container(
    height: 100,
    color: Colors.red,
  ),
),

Config

Default BreakPoint defined like a BootStrap

	width
BP.xs	0 <= w < 576
BP.sm	576 <= w < 768
BP.md	768 <= w < 992
BP.lg	992 <= w < 1200
BP.xl	1200 <= w < double.infinity

but you can change it :

void main() {
  Responsively.instance.breakPoints = BreakPoints(
    xs: 576.0,
    sm: 768.0,
    md: 992.0,
    lg: 1200.0,
    xl: double.infinity
  );
  runApp(MyApp());
}
