How to add Horizontal and Vertical Divider on Flutter

In this example, we are going to show you the easiest way to add a horizontal or vertical divider, change its color, thickness, and width in the Flutter app. See the example below:

How to Add Horizontal Divider:

Divider(
    color: Colors.redAccent, //color of divider
    height: 5, //height spacing of divider
    thickness: 3, //thickness of divier line
    indent: 25, //spacing at the start of divider
    endIndent: 25, //spacing at the end of divider
)

How to Add Vertical Divider:

VerticalDivider(
  color: Colors.black,  //color of divider
  width: 10, //width space of divider
  thickness: 3, //thickness of divier line
  indent: 10, //Spacing at the top of divider.
  endIndent: 10, //Spacing at the bottom of divider.
)

          body: Container(
            padding: EdgeInsets.all(15),
             child: Column(children: [

                    Card(
                      child: Container(
                          height: 50,
                          color: Colors.black12,

                       indent: 25, //spacing at the start of divider
                       endIndent: 25, //spacing at the end of divider

                    ),

                    IntrinsicHeight( //wrap Row with this, otherwise, vertical divider will not display
                      child:Row(

                                ),
                            ),

                            
                            VerticalDivider(
