/// 1、翻页的时候动态计算，只缓存几页的内容，下次翻页的时候再计算
/// 2、https://github.com/flutter/flutter/issues/30604 裁剪canvas
/// 3、平台计算……
/// 4、自己新建一个主isolate？但是不给它任何View？
///
///
/// 评测结果记录：
/// 1、这样不行，这样无法计算上一章的最后一页
/// 2、但是这种方式是基于不自定义段落间距，而固定所有行距实现的，无法自定义
/// 3、但是不能保证Android平台和ios平台自己计算结果和flutter的一致……
/// 4、好像https://pub.dev/packages/flutter_isolate 实现了这点。
