タイポグラフィとシェイプトークン

Just like colors, your text styles live in the theme. The typography slot of MaterialTheme defines every font size, weight, and spacing in one place. 🔤

Material gives you a ready-made type scale: named roles like headline, title, body, and label that keep your text consistent across screens.

You reach a style by name, so a headlineLarge looks the same everywhere and updates app-wide when you tweak the theme once.

Use bodyMedium for paragraphs and titleLarge for headers; picking the right role gives clear hierarchy without hand-tuning every size.

You override a role with a copy, changing only what you need; here titleLarge keeps its size but gets a bolder weight.

Swap the default font by setting a fontFamily on your styles, so your brand typeface flows through every Text in the app.

Corners are themeable as well. The shapes slot defines how rounded your cards, buttons, and sheets look across the app.

Material 3 groups shapes into small, medium, and large tokens, and components automatically pick the size that fits them.

You set corner radii once in a Shapes object, and every component that uses that token instantly adopts the new roundness.

Apply a token directly to a Composable so it matches the theme; here a Surface clips itself with MaterialTheme.shapes.medium.

Centralizing type and shape tokens means new screens look on-brand automatically, and a single edit restyles them all. ✨

You want every card to share the same corner radius app-wide. Where do you set it?

You styled text through the typography scale and rounded corners through shape tokens, so one theme keeps fonts and shapes consistent. 🎉
