Button

Android

Component in Tv Material Compose

Material Design filled button for TV.

Filled buttons are for high emphasis (important, final actions that complete a flow).

Choose the best button for an action based on the amount of emphasis it needs. The more important an action is, the higher emphasis its button should be.

  • See [Button] for high emphasis (important, final actions that complete a flow).
  • See [OutlinedButton] for a medium-emphasis button with a border.

The default text style for internal [Text] components will be set to [Typography.labelLarge].
