Sometimes it can be difficult to figure out why a Text widget overflows rather than wrapping. For example: #4115. Here's a simple app that demonstrates the problem: import 'package:flutter/material.dart'; class DemoApp extends StatelessW...
文本小部件需要知道它的宽度来 Package 它的文本，因此它应该在ConstrainedBox小部件中。工作代码：
///传入FocusNode,用于监听TextField获取焦点事件 final FocusNode focusNode; /// The child widget that we are wrapping final Widget child; /// The curve we will use to scroll ourselves into view. /// /// Defaults to Curves.ease. final Curve curve; /// The duration we will use to scroll...

The specific widget that could not find a Directionality ancestor was: RichText softWrap: wrapping at box width maxLines: unlimited text: "动画状态 : null" dirty The ownership chain for the affected widget is: "RichText ← Text ← Column ← Padding ← Container ← AnimationApp ← [root]" ...
RichText widgets require a Directionality widget ancestor. The specific widget that could not find a Directionality ancestor was: RichText softWrap: wrapping at box width maxLines: unlimited text: "动画状态 : null" dirty The ownership chain for the affected widget is: "RichText ← Text ← Column...
当Text 或 EditableText 小部件在其构造函数中没有显式指定 textHeightBehavior 时,它们会从其构建上下文中查找最近的 DefaultTextHeightBehavior 并应用找到的行为。如果在小部件树中找不到 DefaultTextHeightBehavior,则这些文本小部件将使用 Flutter 的默认行高行为。
'textDirectionToAxisDirection' 是 Flutter 中的一个函数,用于将文本方向转换为轴方向。在 Flutter 开发中,可以使用它来确定文字排列的方向,以便正确显示文本。在使用 'textDirectionToAxisDirection' 函数时,需要传入两个参数:文本方向(TextDirection)和水平布局方向(AxisDirection),它们分别表示当前文本的方向和布局的方...
