尾随小部件占用整个平铺宽度。请使用大小的小部件，或考虑用自定义小部件替换 ListTile

来自关于 tailing 属性的文档：

/// To show right-aligned metadata (assuming left-to-right reading order;
/// left-aligned for right-to-left reading order),consider using a [Row] with
/// [CrossAxisAlignment.baseline] alignment whose first item is [Expanded] and
/// whose second child is the metadata text,instead of using the [trailing]
/// property.

如果您需要右侧有 2 个图标，我认为您不应该使用 ListTile。相反，您应该使用 Rows 实现您的自定义小部件。

编辑：

类似于：

InkWell( // Only wrap with an Inkwell if you need to add a click for the entire Row
  onTap: ...
  child: Row(
    crossAxisAlignment: CrossAxisAlignment.baseline,children: [
      CircleAvatar(...),Expanded(child: Text(title)),Row(
        children: [
          IconButton1,IconButton2,],),]
  ),)

我所做的是用一个容器将行（尾随：Row()）包裹起来，并给它一个特定的宽度

import 'package:flutter/material.dart';

class UserProductItem extends StatelessWidget {
  final String title;
  final String imageUrl;
  UserProductItem(this.title,this.imageUrl);

  @override
  Widget build(BuildContext context) {
    return InkWell(
      child: ListTile(
        title: Text(title),leading: CircleAvatar(
          backgroundImage: NetworkImage(imageUrl),trailing: Container(
          width: 100,child: Row(
            children: [
              IconButton(
                icon: Icon(Icons.edit),onPressed: () {},color: Theme.of(context).primaryColor,IconButton(
                icon: Icon(Icons.delete),color: Theme.of(context).errorColor,)
            ],);
  }
}
