如何在 flutter 中自定义带有持续时间的文本动画

Question

我有一个带有动画持续时间的文本列表

List<RhymeModel> rhymePhrases = [
  RhymeModel(lyricsPhrase: 'Baa, baa', startAt: 0.0, endAt: 0.2),
  RhymeModel(lyricsPhrase: 'black sheep', startAt: 0.3, endAt: 0.4),
  RhymeModel(lyricsPhrase: 'Have you', startAt: 0.5, endAt: 0.6),
  RhymeModel(lyricsPhrase: 'any wool?', startAt: 0.7, endAt: 0.8),
  RhymeModel(lyricsPhrase: 'Yes, sir,', startAt: 0.9, endAt: 1.0),
  RhymeModel(lyricsPhrase: 'yes, sir,', startAt: 1.1, endAt: 1.2),
  RhymeModel(lyricsPhrase: 'Three bags full.', startAt: 1.3, endAt: 1.4),
  RhymeModel(lyricsPhrase: 'One for the master,', startAt: 1.5, endAt: 1.6),
  RhymeModel(lyricsPhrase: 'And one for', startAt: 1.7, endAt: 1.8),
  RhymeModel(lyricsPhrase: 'dame,And one', startAt: 1.9, endAt: 2.0),
  RhymeModel(lyricsPhrase: 'for the little', startAt: 2.1, endAt: 2.2),
  RhymeModel(lyricsPhrase: 'boy Who lives ', startAt: 2.3, endAt: 2.4),
  RhymeModel(lyricsPhrase: 'down the lane.', startAt: 2.5, endAt: 2.6),
];

我的目标是使用持续时间通过显示动画为每个文本设置动画（类似于歌词与音频匹配时看到的内容）如何用动画为每个文本设置动画？
