Responsive Grid / Grid System

Example: example.dart

Grid system is very important when you create some web application. Especially for create responsive layout. This plugin is help to solve it

To create responsive layout you must using widget BsRow and BsCol or if in bootstrap use class="row" and class="col-*"

Create row container of grid system:

BsRow(
  gutter: EdgeInsets.only(left: 10.0, right: 10.0, top: 5.0, bottom: 5.0),
  children: <BsCol>[
    // ...
  ]
);

After that you can add column:

BsRow(
//...
    children: <BsCol>[
      BsCol(
        decoration: BoxDecoration(
          border: Border.all(color: Colors.black),
        ),
        padding: EdgeInsets.all(20.0),
        sizes: ColScreen(sm: Col.col_12, lg: Col.col_6),
        child: Center(child: Text('col-sm-12 col-lg-6')),
      ),
      BsCol(
        decoration: BoxDecoration(
          border: Border.all(color: Colors.black),
        ),
        visibility: BsVisibility.hiddenMd,
        padding: EdgeInsets.all(20.0),
        sizes: ColScreen(sm: Col.col_12, lg: Col.col_6),
        child: Center(child: Text('col-sm-12 col-lg-6 col-hidden-md')),
      ),
      BsCol(
        decoration: BoxDecoration(border: Border.all(color: Colors.black)),
        padding: EdgeInsets.all(20.0),
        sizes: ColScreen(sm: Col.col_12, md: Col.col_12, lg: Col.col_6),
        order: ColOrder(md: 1),
        child: Center(child: Text('col-sm-12 col-md-12 col-md-6 col-order-lg-1')),
      ),
      BsCol(
        decoration: BoxDecoration(border: Border.all(color: Colors.black)),
        padding: EdgeInsets.only(top: 10.0, bottom: 10.0),
        sizes: ColScreen(md: Col.col_6),
        child: BsRow(
          children: [
            BsCol(
              decoration: BoxDecoration(
                color: Colors.white,
                border: Border.all(color: Colors.black),
              ),
              padding: EdgeInsets.all(10.0),
              sizes: ColScreen(md: Col.col_4),
              child: Center(child: Text('Nested col-md-4')),
            ),
            BsCol(
              decoration: BoxDecoration(
                color: Colors.white,
                border: Border.all(color: Colors.black),
              ),
              padding: EdgeInsets.all(10.0),
              sizes: ColScreen(md: Col.col_4),
              offset: ColScreen(lg: Col.col_4),
              child: Center(child:Text('Nested col-md-4 col-offset-lg-4')),
            ),
          ],
        ),
      ),
    ] 
// ...
)

Note

• Properties sizes in BsCol is has default value Col.col_12 or 100% of screen width
• If need to ordering column use properties order with value BsScreen
• If need to custom offset of column use properties offet with value BsScreen
• BsVisibility.hiddenMd will hide widget in max screen medium or < 768 px, above it will show
