themes/_scale_text_style library

Functions

scaleOptionalTextStyle(TextStyle? style, double factor, double defaultFontSize) → TextStyle?

Like scaleTextStyle but preserves null: if style is null, returns null without materializing a TextStyle from defaultFontSize. Used for opt-in styles such as ChildNodeTheme.selectedTextStyle and NodeTooltipTheme.textStyle.

scaleTextStyle(TextStyle? style, double factor, double defaultFontSize) → TextStyle

Returns a scaled copy of style, resolving a null fontSize against defaultFontSize before multiplying.
