根因分析

在Text小部件上同时设置overflow: TextOverflow.ellipsis和maxLines，但父级约束过于严格，导致文本被意外裁剪而非显示省略号。

English

Setting both overflow: TextOverflow.ellipsis and maxLines on a Text widget while the parent constraints are too tight, causing the text to be clipped unexpectedly instead of showing ellipsis.

解决方案

  1. Use a Flexible or Expanded parent widget to give the Text widget adequate width for ellipsis to work.
  2. Set textWidthBasis: TextWidthBasis.longestLine on the Text widget to improve ellipsis calculation.

无效尝试

常见但无效的做法:

  1. 55% 失败

    Without maxLines, the text may expand infinitely, causing overflow errors in the parent widget.

  2. 45% 失败

    softWrap: false disables line breaking entirely, leading to RenderFlex overflow warnings.

  3. 35% 失败

    FittedBox scales the entire text widget, potentially making it unreadable at small sizes.
