stepper_flutter_form
是一个用于 Flutter 的插件,用于创建带有表单的步进器(Stepper)。它允许用户通过多个步骤来完成表单填写,每个步骤可以包含不同的表单字段。
以下是如何使用 stepper_flutter_form
插件的基本步骤:
1. 添加依赖
首先,你需要在 pubspec.yaml
文件中添加 stepper_flutter_form
插件的依赖:
dependencies:
flutter:
sdk: flutter
stepper_flutter_form: ^1.0.0 # 请检查最新版本
然后运行 flutter pub get
来安装依赖。
2. 导入插件
在你的 Dart 文件中导入 stepper_flutter_form
插件:
import 'package:stepper_flutter_form/stepper_flutter_form.dart';
3. 创建步进器表单
你可以使用 StepperFlutterForm
组件来创建一个步进器表单。以下是一个简单的示例:
class MyForm extends StatefulWidget {
@override
_MyFormState createState() => _MyFormState();
}
class _MyFormState extends State<MyForm> {
final _formKey = GlobalKey<FormState>();
int _currentStep = 0;
List<Step> _steps = [
Step(
title: Text('Step 1'),
content: TextFormField(
decoration: InputDecoration(labelText: 'Name'),
validator: (value) {
if (value == null || value.isEmpty) {
return 'Please enter your name';
}
return null;
},
),
),
Step(
title: Text('Step 2'),
content: TextFormField(
decoration: InputDecoration(labelText: 'Email'),
validator: (value) {
if (value == null || value.isEmpty) {
return 'Please enter your email';
}
return null;
},
),
),
Step(
title: Text('Step 3'),
content: TextFormField(
decoration: InputDecoration(labelText: 'Password'),
obscureText: true,
validator: (value) {
if (value == null || value.isEmpty) {
return 'Please enter your password';
}
return null;
},
),
),
];
void _submitForm() {
if (_formKey.currentState!.validate()) {
// 表单验证通过,处理表单数据
print('Form submitted successfully');
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Stepper Form'),
),
body: Form(
key: _formKey,
child: StepperFlutterForm(
steps: _steps,
currentStep: _currentStep,
onStepContinue: () {
if (_currentStep < _steps.length - 1) {
setState(() {
_currentStep += 1;
});
} else {
_submitForm();
}
},
onStepCancel: () {
if (_currentStep > 0) {
setState(() {
_currentStep -= 1;
});
}
},
),
),
);
}
}
4. 运行应用
在你的 main.dart
文件中运行应用:
void main() {
runApp(MaterialApp(
home: MyForm(),
));
}
