Root Cause

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.

generic

中文

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。

  2. Set textWidthBasis: TextWidthBasis.longestLine on the Text widget to improve ellipsis calculation.

Dead Ends

Common approaches that don't work:

  1. 55% fail

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

  2. 45% fail

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

  3. 35% fail

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