You can set the width of the Text component to be the same as the font size to achieve the purpose. The code snippet is as follows:
@Entry
@Component
struct Index {
private message: string = 'This document is suitable for beginners in application development. By building a simple application with page jump/return function, quickly understand the main files of the project directory and familiarize yourself with the application development process.';
build() {
Column() {
Text(this.message)
.fontSize(13)
.width(13)
}
}
}
