decodeOutlinedBorder static method

OutlinedBorder? decodeOutlinedBorder(dynamic value, { bool validate = true, })

Decodes a given Map-like value into a OutlinedBorder. The value returned depends on the "type" parameter. The "type" must be one of:

• beveled
• circle
• rectangle
• rounded
• stadium

The JSON format of the value depends on the "type" and the associated class.

BeveledRectangleBorder

{
  "borderRadius": <BorderRadius>,
  "side": <BorderSide>,
  "type": "beveled"
}

CircleBorder

{
  "side": <BorderSide>,
  "type": "circle"
}

ContinuousRectangleBorder

{
  "borderRadius": <BorderRadius>,
  "side": <BorderSide>,
  "type": "rectangle"
}

RoundedRectangleBorder

{
  "borderRadius": <BorderRadius>,
  "side": <BorderSide>,
  "type": "rounded"
}

StadiumBorder

{
  "side": <BorderSide>,
  "type": "stadium"
}
