font, fontWeight, and fontDesign choose the typeface, weight, and variant. bold, italic, monospaced, strikethrough, and underline are convenience toggles for common styles and decorations.
tracking and lineSpacing adjust spacing between letters and lines. textCase transforms case at render time. lineLimit and multilineTextAlignment control how text wraps and aligns across multiple lines.

Adjusts letter spacing in text.MilliEm
required
The letter spacing to add between characters.
MilliEm is an alias for number, and every renderer applies the value as a length: points on iOS, CSS pixels on web, and sp on Android. Use positive values to increase spacing or negative values to tighten.tracking does not scale with the font size. For example, tracking(4) adds 4pt of spacing between each character on iOS, the same as CSS letter-spacing: 4px on web.
Wide letter spacing
lineSpacing
Adjusts spacing between lines of text.number
