AnimatedTextSequence class

Cycles through a list of SequenceText items with optional transitions between them.

Each item is displayed for displayDuration, after which a transition lasting transitionDuration switches to the next text. The transition reuses TextEffect classes — when transitionEffect is provided, it is applied to both the outgoing and incoming text as a whole.

AnimatedTextSequence(
  texts: [
    SequenceText('Hello', effects: [FadeEffect(), WaveEffect()]),
    SequenceText('World', effects: [SlideEffect()]),
  ],
  transitionEffect: FadeEffect(),
)
