Flutter give container rounded border

Question

I'm making a Container() , I gave it a border, but it would be nice to have rounded borders.

This is what I have now:

Container(
      width: screenWidth / 7,
      decoration: BoxDecoration(
        border: Border.all(
          color: Colors.red[500],
        ),
      ),
      child: Padding(
        padding: EdgeInsets.all(5.0),
        child: Column(
          children: <Widget>[
            Text(
              '6',
              style: TextStyle(
                  color: Colors.red[500],
                  fontSize: 25),
            ),
            Text(
             'sep',
              style: TextStyle(
                  color: Colors.red[500]),
            )
          ],
        ),
      ),
    );

I tried putting ClipRRect on it, but that crops the border away. Is there a solution for this?

Answer 1

Try using the property borderRadius from BoxDecoration

Something like

Container(
  decoration: BoxDecoration(
    border: Border.all(
      color: Colors.red[500],
    ),
    borderRadius: BorderRadius.all(Radius.circular(20))
  ),
  child: ...
)

Answer 2

To make it completely circle:

Container(
      decoration: BoxDecoration(
        shape: BoxShape.circle,
      ),
    )

To make it a circle at selected spots:

Container(
      decoration: BoxDecoration(
        borderRadius: BorderRadius.only(
            topRight: Radius.circular(40.0),
            bottomRight: Radius.circular(40.0),
            topLeft: Radius.circular(40.0),
            bottomLeft: Radius.circular(40.0)),
      ),
      child: Text("hello"),
    ),

or

  Container(
      decoration: BoxDecoration(
        borderRadius: BorderRadius.all(Radius.circular(20)),
      ),
      child: ...
    )

Answer 3

You can use like this. If you want border for all the corners you can use like bellow.

Container(
  decoration: BoxDecoration(
    color: Colors.white,
    borderRadius: BorderRadius.all(
      Radius.circular(12.0),
    ),
  ),
),

If you want rounded borders for selected sides only you can use like below.

Container(
  decoration: BoxDecoration(
    color: Colors.white,
    borderRadius: BorderRadius.only(
      topLeft: Radius.circular(10),
      topRight: Radius.circular(10),
    ),
  ),
  child: Text('Text'),
),

Answer 4

You can use ClipRRect Widget:

ClipRRect (
  borderRadius: BorderRadius.circular(5.0),
  child: Container(
                    height: 25,
                    width: 40,
                    color: const Color(0xffF8742C),
                    child: Align(
                        alignment: Alignment.center,
                        child: Text("Withdraw"))),
          )

Answer 5

Enhancement for the above answer.

Container(
  decoration: BoxDecoration(
    border: Border.all(
      color: Colors.red[500],
    ),
   borderRadius: BorderRadius.circular(20) // use instead of BorderRadius.all(Radius.circular(20))
  ),
  child: ...
)

Answer 6

To make a complete circle just use shape property :

Container(
   padding: const EdgeInsets.all(4),
   decoration: BoxDecoration(
     shape: BoxShape.circle,
     color: Colors.black,
   ),                            
   child: Icon(
      Icons.add,
      size: 15.0,
      color: Colors.white,
     ),
                               
                                

Answer 7

Container(
    decoration: BoxDecoration(
      borderRadius: BorderRadius.circular(20.0),
      border: Border.all(
        color: HexColor('#C88A3D'),
        width: 3.0
      )
    ),
    child: Container(
      decoration: new BoxDecoration(borderRadius:
      BorderRadius.circular(20.0),
      color: Colors.white,),
    )
  ),

Answer 8

The key here is to add a BorderRadius :

Container(    
  decoration: BoxDecoration(
    border: Border.all(
      color: Colors.red[340],
     ),
     borderRadius: BorderRadius.all(Radius.circular(35),
   ),
   child: `enter code here`
),

Answer 9

just with put this at the Container

Container(
  decoration: BoxDecoration(
    borderRadius: BorderRadius.all(Radius.circular(30))
  ),
)

Answer 10

Just to show another way to do the same thing.

Might be useful when needs to use InkWell around Container.

Material(
 shape: RoundedRectangleBorder(
   borderRadius: BorderRadius.circular(8),
 ),
 child: Container(
   height: 100,
   width: 150,
 ),
);

Answer 11

Just simply use circle shape shape: BoxShape.circle in BoxDecoration . All code be like

Container(
  decoration: BoxDecoration(
    shape: BoxShape.circle
  ),
)

Answer 12

SizedBox(
                            child: (Container(
                              decoration: BoxDecoration(
                                  color: Colors.grey,
                                  border: Border.all(
                                    color: Colors.grey,
                                  ),
                                  borderRadius:
                                      BorderRadius.all(Radius.circular(20))),
                              child: Column(
                                mainAxisAlignment:
                                    MainAxisAlignment.spaceBetween,
                                crossAxisAlignment: CrossAxisAlignment.center,
                                children: [
                                  Row(
                                    mainAxisAlignment:
                                        MainAxisAlignment.spaceAround,
                                    crossAxisAlignment:
                                        CrossAxisAlignment.center,
                                    children: [
                                      Text('00'),

                                      Padding(
                                        padding: const EdgeInsets.fromLTRB(
                                            2.0, 0, 0, 0),
                                        child: Container(
                                          padding: const EdgeInsets.all(8),
                                          decoration: BoxDecoration(
                                            shape: BoxShape.circle,
                                            color: Colors.white,
                                          ),
                                          child: CustomText(
                                            "2",
                                            color: Colors.black,
                                          ),
                                        ),
                                      ), // text
                                    ],
                                  ),
                                ],
                              ),
                            )),
                            width: 60,
                          ),

Answer 13

It can be done in many different ways.

• If you have a simple rounded corner to implement use ClipRRect , ClipOval
• If you want to have more command over the rounded corneres use BoxDecoration inside the Container

ClipRRect

 ClipRRect(
    borderRadius: BorderRadius.circular(20),
    child: Container(height: 100, width: 100, color: Colors.orange)),

ClipOval

ClipOval(
    child: Container(height: 100, width: 100, color: Colors.orange)),

BoxDecoration

• Border across all the corners

 Container(
   decoration: BoxDecoration(
   borderRadius: BorderRadius.circular(10),
   color: Colors.orange),
   height: 100,
   width: 100,
 );

• Border in a particular corner

 Container(
    decoration: const BoxDecoration(
      borderRadius: BorderRadius.only(
       topLeft: Radius.circular(40),
       bottomRight: Radius.circular(40)),
      color: Colors.orange),
    height: 100,
    width: 100,
 ),

• Border in a particular axis

  Container(
    decoration: const BoxDecoration(
      borderRadius: BorderRadius.horizontal(
        right: Radius.circular(60),
        ),
      color: Colors.orange),
    height: 100,
    width: 100,
  );

Answer 14

use decoration property to give radius in Container

 decoration: BoxDecoration(
        borderRadius: BorderRadius.only(
            topRight: Radius.circular(15),
            bottomLeft: Radius.circular(15)),
      ),

or 

Container(
  decoration: BoxDecoration(
    color: Colors.red,
    borderRadius: BorderRadius.all(
      Radius.circular(12.0),

    ),
  ),
),
