Flutter类中段落的含义 [英] Meaning of Paragraph in Flutter classes

问题描述

Flutter中有几个类和方法的名称带有"Paragraph".例子:

There are several classes and methods in Flutter that have "Paragraph" in the name. Examples:

• 段落
• ParagraphBuilder
• RenderParagraph
• ParagraphStyle
• Canvas.drawParagraph

• Paragraph
• ParagraphBuilder
• RenderParagraph
• ParagraphStyle
• Canvas.drawParagraph

这里的段落是什么意思?通常，我认为一段文本是一些没有换行符的句子. Flutter段落可以包含多行吗?

What is the meaning of paragraph here? Usually I think of a paragraph of text as a few of sentences with no new line characters. Can a Flutter paragraph contain multiple new lines?

文档不清楚:

The documentation isn't clear:

段落类

一段文字.

推荐答案

Flutter段落可以包含多个换行符.这可以通过在ParagraphBuilder或TextPainter中使用以下文本字符串来演示，该文本字符串会在Flutter的意义上创建单个Paragraph.

A Flutter Paragraph can contain more that one newline character. This can be demonstrated by using the following text string in a ParagraphBuilder or a TextPainter, which creates a single Paragraph in the Flutter sense of the word.

final text = 'My text line.\nThis line is longer than the last.\nAnother line.';
