estimateErrorBrightness static method

Brightness estimateErrorBrightness(
  1. Color color
)

Brightness estimation for error colors that includes fix to consider M2 spec for on M2 dark error color.

Implementation

static Brightness estimateErrorBrightness(Color color) {
  // The ThemeData.estimateBrightnessForColor returns dark on the M2
  // Material dark mode error colors, but M2 spec uses black onColor on it
  // so we should return light to get the correct on color for
  // materialDarkError.
  if (color == FlexColor.materialDarkError) return Brightness.light;
  if (color == FlexColor.materialDarkErrorHc) return Brightness.light;
  // Might as well do this as quick return too, estimateBrightnessForColor
  // returns same value for this color, but since we will be using this logic
  // for error colors we might as well use results for other hard coded color
  // values and not call ThemeData.estimateBrightnessForColor
  if (color == FlexColor.materialLightError) return Brightness.dark;
  if (color == FlexColor.materialLightErrorHc) return Brightness.dark;
  // For other error colors we estimate the brightness.
  return ThemeData.estimateBrightnessForColor(color);
