如何在 Flutter 中进行逐行搜索和文本？

Question

我试图让它排成一行，但是屏幕上什么都没有。 在Flutter怎么解决？

应用栏

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(vertical: 20, horizontal: 10.0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: [
          const Text(
            "Goals",
            style: TextStyle(fontSize: 16, fontWeight: FontWeight.bold),

搜索

@override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 10),
      child: Container(
        height: 55,
        decoration: BoxDecoration(
          color: Colors.grey[200],
        ),
        child: TextFormField(
          decoration: const InputDecoration(
            prefixIcon: Icon(Icons.search),
            hintText: "Search",
            hintStyle: TextStyle(
              color: Colors.black,
            ),
            enabledBorder: OutlineInputBorder(
              borderSide: BorderSide.none,
            ),
            focusedBorder: OutlineInputBorder(
              borderSide: BorderSide.none,
            ),
          ),
        ),
      ),
    );

在屏幕中我尝试将这两个小部件放在行中，但不起作用

return Scaffold(
      body: SafeArea(
        child: ListView(
          children: <Widget>[
            const CustomAppBar(),
            const SearchBar(),

这是我的结果：

您可以使用CupertinoSearchTextField()

来自文档的示例

Padding(
  padding: const EdgeInsets.all(8.0),
  child: Center(
    child: CupertinoSearchTextField(),
  ),
),

 Row(
  children: [
    Padding(
      padding: const EdgeInsets.all(8.0),
      child: Text("Goals"),
    ),
    Expanded(child: CupertinoSearchTextField()),
  ],
),
