在ListView构建器中实现搜索

TextField(
  onChanged: (value) {
    // 在这里处理搜索框内容变化的逻辑
  },
)

ListView.builder(
  itemCount: data.length,
  itemBuilder: (context, index) {
    // 过滤数据
    final filteredData = data.where((item) => item.contains(searchText)).toList();

    // 显示过滤后的数据
    return ListTile(
      title: Text(filteredData[index]),
    );
  },
)

final filteredData = data.where((item) => item.contains(searchText)).toList();

Column(
  children: [
    TextField(
      onChanged: (value) {
        setState(() {
          searchText = value;
        });
      },
    ),
    Expanded(
      child: ListView.builder(
        itemCount: data.length,
        itemBuilder: (context, index) {
          final filteredData = data.where((item) => item.contains(searchText)).toList();
          return ListTile(
            title: Text(filteredData[index]),
          );
        },
      ),
    ),
  ],
)
