以下是我当前拥有的代码
import 'package:flutter/material.dart';
import 'package:finsec/widget/text_form_field.dart';
void main() {
runApp(MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Simple Interest Calculator App',
home: ThirdFragment(),
theme: ThemeData(
brightness: Brightness.dark,
primaryColor: Colors.indigo,
accentColor: Colors.indigoAccent),
));
}
class ThirdFragment extends StatefulWidget {
@override
State<StatefulWidget> createState() {
return _ThirdFragmentState();
}
}
class _ThirdFragmentState extends State<ThirdFragment> {
var _formKey = GlobalKey<FormState>();
var _currencies = ['Rupees', 'Dollars', 'Pounds'];
final double _minimumPadding = 5.0;
var _currentItemSelected = '';
@override
void initState() {
super.initState();
_currentItemSelected = _currencies[0];
// principalController.addListener(onChange);
}
TextEditingController principalController = TextEditingController();
TextEditingController roiController = TextEditingController();
TextEditingController termController = TextEditingController();
var displayResult = '';
@override
Widget build(BuildContext context) {
TextStyle textStyle = Theme.of(context).textTheme.title;
return Scaffold(
// resizeToAvoidBottomPadding: false,
appBar: AppBar(
title: Text('Simple Interest Calculator'),
),
body: Form(
key: _formKey,
child: GridView.count(
crossAxisCount: 2,
crossAxisSpacing: 0,
padding: const EdgeInsets.all(10.0),
children: List.generate(2, (index) {
return
Text(
'Item $index',
style: Theme.of(context).textTheme.headline,
);
}),
)
),
);
}
}
我正在尝试在文本左侧添加一个文本,在文本右侧添加一个文本输入字段。目前,我正在显示文本,因为我不确定如何添加文本字段。另外,两个文本之间的间距太大,我想减小间距。预先感谢
到目前为止,这是我的输出
im寻找类似下面的输出。我添加的每个文本框都应在另一个框下面排成一行,并且该文本应在该文本框之间居中。 以下是我要完成的示例。注意文本字段 阵容
答案 0 :(得分:1)
这里有一个示例,您可以使用<figure class="woocom-project">
<div class="woo-buttons-on-img">
<a href="#" class="alignnone layzr-bg-transparent"></a>
</div>
<figcaption class="woocom-list-content">
<h4 class="entry-title">
<a href="#" title="product description" rel="bookmark">product description</a>
</h4>
<span class="custom-attributes"><span class="range alma"><span class="attribute-value">range name,</span></span><br></span>
<span class="price"><span class="woocommerce-Price-amount amount"><span class="woocommerce-Price-currencySymbol">£</span>838.00</span></span>

而不是ListView.builder
来实现所需的功能。
GridView
如果仍然需要使用Form(
key: _formKey,
child: ListView.builder(
padding: const EdgeInsets.all(10.0),
itemCount: 10,
itemBuilder: (context, index) {
return Row(children: [
Expanded(
child: Text(
'Item $index',
maxLines: 1,
style: Theme.of(context).textTheme.headline,
),
),
Expanded(
flex: 2,
child: TextField(
decoration: InputDecoration(
hintText: "Hint $index",
),
),
),
]);
}),
),
,则可以使用以下逻辑:
GridView
