我正在尝试创建一个中心文本具有最大大小的行，如果文本内容太大，它适合大小。

我插入 TextOverflow.ellipsis 属性以缩短文本并插入三点 ... 但它不起作用。

main.dart

nhập 'gói:flutter/material.dart';

hàm main() {
runApp(MyApp mới());
}

lớp MyApp mở rộng StatelessWidget {
  @ghi đè
  Xây dựng tiện ích (BuildContext context) {
    trả về MaterialApp mới(
      home: new HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @ghi đè
  Widget build(BuildContext context) => new Scaffold(
    appBar: AppBar mới(
      backgroundColor: new Color(0xFF26C6DA),
    ),

您应该将您的 Container 包装在 Flexible 中让您的 Hàng ngang Biết Container 比其固有宽度窄是可以的。 Expanded也可以。

Flexible(
  child: new Container(
    padding: new EdgeInsets.only(right: 13.0),
    child: new Text(
      'Text largeeeeeeeeeeeeeeeeeeeeeee',
      overflow: TextOverflow.ellipsis,
      style: new TextStyle(
        fontSize: 13.0,
        fontFamily: 'Roboto',
        color: new Color(0xFF212121),
        fontWeight: FontWeight.bold,
      ),
    ),
  ),
),
