applyToBorderRadius method

BorderRadiusGeometry applyToBorderRadius(BorderRadiusGeometry borderRadius, TextDirection textDirection)

Applies corner multipliers to a border radius.

Multiplies each corner's radius by the corresponding corner value, properly handling text direction for start/end mapping to left/right.

Parameters:

• borderRadius: The base border radius to modify
• textDirection: Text direction for resolving start/end to left/right

Returns a new BorderRadiusGeometry with modified corner radii.

Implementation

BorderRadiusGeometry applyToBorderRadius(
    BorderRadiusGeometry borderRadius, TextDirection textDirection) {
  final topLeftValue =
      textDirection == TextDirection.ltr ? topStartValue : topEndValue;
  final topRightValue =
      textDirection == TextDirection.ltr ? topEndValue : topStartValue;
  final bottomLeftValue =
      textDirection == TextDirection.ltr ? bottomStartValue : bottomEndValue;
  final bottomRightValue =
      textDirection == TextDirection.ltr ? bottomEndValue : bottomStartValue;
  final resolvedBorderRadius = borderRadius.resolve(textDirection);
  return BorderRadius.only(
    topLeft: Radius.elliptical(
      resolvedBorderRadius.topLeft.x * topLeftValue,
      resolvedBorderRadius.topLeft.y * topLeftValue,
    ),
    topRight: Radius.elliptical(
      resolvedBorderRadius.topRight.x * topRightValue,
      resolvedBorderRadius.topRight.y * topRightValue,
    ),
    bottomLeft: Radius.elliptical(
      resolvedBorderRadius.bottomLeft.x * bottomLeftValue,
      resolvedBorderRadius.bottomLeft.y * bottomLeftValue,
    ),
    bottomRight: Radius.elliptical(
      resolvedBorderRadius.bottomRight.x * bottomRightValue,
      resolvedBorderRadius.bottomRight.y * bottomRightValue,
    ),
  );
