colorToHex function

String? colorToHex(
  1. String color
)

Decides the color format type and converts it to hexadecimal format.

Detects the type of color from color and calls the corresponding conversion function:

  • If color starts with 'rgb(', converts it using rgbToHex.
  • If color starts with 'rgba(', converts it using rgbaToHex.
  • If color starts with 'hsl(', converts it using hslToHex.
  • If color starts with 'hsla(', converts it using hslaToHex. Throws ArgumentError if the color format is not supported.

Parameters:

  • color: The input color string to convert to hexadecimal format.

Returns: The converted color string in hexadecimal format.

Example:

print(colorToHex('rgb(255, 0, 0)')); // Output: #ff0000
print(colorToHex('hsla(0, 100%, 50%, 0.5)')); // Output: #ff0000

Implementation

String? colorToHex(String color) {
  // Detectar el tipo de color y llamar a la función correspondiente
  if (color.startsWith('rgb(')) {
    return rgbToHex(color);
  } else if (color.startsWith('rgba(')) {
    return rgbaToHex(color);
  } else if (color.startsWith('hsl(')) {
    return hslToHex(color);
  } else if (color.startsWith('hsla(')) {
    return hslaToHex(color);
  } else {
    return null;
  }
}
