CupertinoDatePicker、CupertinoTimerPicker 是 iOS 风格的 DatePickerView 和 TimePickerView 的日期时间选择器。
1. CupertinoTimerPicker
CupertinoDatePicker 定义
CupertinoDatePicker({
Key? key,
this.mode = CupertinoDatePickerMode.dateAndTime,
required this.onDateTimeChanged,
DateTime? initialDateTime,
this.minimumDate,
this.maximumDate,
this.minimumYear = 1,
this.maximumYear,
this.minuteInterval = 1,
this.use24hFormat = false,
this.dateOrder,
this.backgroundColor,
})
CupertinoDatePicker 属性
| CupertinoDatePicker 属性 | 介绍 |
|---|---|
| mode | CupertinoDatePickerMode 日期选择器模式 ,time,date,dateAndTime, 默认dateAndTime
|
| onDateTimeChanged | @required 选中日期变化回调 |
| initialDateTime | 当前日期 |
| minimumDate | 最小可选日期 |
| maximumDate | 最大可选日期 |
| minimumYear | 最小年份 |
| maximumYear | 最大年份 |
| minuteInterval | 分钟间隔 initialDateTime.minute 必须可以整除 minuteInterval 必须是 60 的整数因子 |
| use24hFormat | 是否使用24小时制 |
| dateOrder | 期选择器排序方式 默认年/月/日 |
| backgroundColor | 背景色 |
2. CupertinoDatePicker 实例
注意：取消、确认按钮是自己绘制的，不是cupertinoDatePicker提供的
示例1 CupertinoDatePickerMode.date
final CupertinoDatePicker cupertinoDatePicker = CupertinoDatePicker(
mode: CupertinoDatePickerMode
.date, // 日期选择器模式 `time`,`date`,`dateAndTime`, 默认`dateAndTime`
initialDateTime: DateTime.now(), // 初始化日期
minimumDate: DateTime(2021, 10, 10), // 最小可选日期
maximumDate: DateTime(2023, 12, 22), // 最大可选日期
minimumYear: 2020, // 最小年份
maximumYear: 2025, // 最大年份
minuteInterval:
1, // 分钟间隔 initialDateTime.minute 必须可以整除 minuteInterval 必须是 60 的整数因子
use24hFormat: true, // 是否使用24小时制
dateOrder: DatePickerDateOrder.dmy, // 日期选择器排序方式 默认年/月/日
backgroundColor: Colors.white,
// 选中日期变化回调
onDateTimeChanged: (dateTime) {
_chooseDateTime = dateTime;
},
);
image.png
示例2 CupertinoDatePickerMode.dateAndTime
final CupertinoDatePicker cupertinoDatePicker = CupertinoDatePicker(
mode: CupertinoDatePickerMode
.dateAndTime, // 日期选择器模式 `time`,`date`,`dateAndTime`, 默认`dateAndTime`
initialDateTime: DateTime.now(), // 初始化日期
minimumDate: DateTime(2021, 10, 10), // 最小可选日期
maximumDate: DateTime(2023, 12, 22), // 最大可选日期
minimumYear: 2020, // 最小年份
maximumYear: 2025, // 最大年份
minuteInterval:
1, // 分钟间隔 initialDateTime.minute 必须可以整除 minuteInterval 必须是 60 的整数因子
use24hFormat: false, // 是否使用24小时制
dateOrder: DatePickerDateOrder.ymd, // 日期选择器排序方式 默认年/月/日
backgroundColor: Colors.white,
// 选中日期变化回调
onDateTimeChanged: (dateTime) {
_chooseDateTime = dateTime;
},
);
image.png
示例3 CupertinoDatePickerMode.time
final CupertinoDatePicker cupertinoDatePicker = CupertinoDatePicker(
mode: CupertinoDatePickerMode
.time, // 日期选择器模式 `time`,`date`,`dateAndTime`, 默认`dateAndTime`
initialDateTime: DateTime.now(), // 初始化日期
minimumDate: DateTime(2021, 10, 10), // 最小可选日期
maximumDate: DateTime(2023, 12, 22), // 最大可选日期
minimumYear: 2020, // 最小年份
maximumYear: 2025, // 最大年份
minuteInterval:
1, // 分钟间隔 initialDateTime.minute 必须可以整除 minuteInterval 必须是 60 的整数因子
use24hFormat: false, // 是否使用24小时制
dateOrder: DatePickerDateOrder.ymd, // 日期选择器排序方式 默认年/月/日
backgroundColor: Colors.white,
// 选中日期变化回调
onDateTimeChanged: (dateTime) {
_chooseDateTime = dateTime;
},
);

3. CupertinoTimerPicker
CupertinoTimerPicker 定义
CupertinoTimerPicker({
Key? key,
this.mode = CupertinoTimerPickerMode.hms,
this.initialTimerDuration = Duration.zero,
this.minuteInterval = 1,
this.secondInterval = 1,
this.alignment = Alignment.center,
this.backgroundColor,
required this.onTimerDurationChanged,
})
CupertinoTimerPicker 属性
| CupertinoTimerPicker 属性 | 介绍 |
|---|---|
| mode | CupertinoTimerPickerMode,时间选择器模式 ,hm,ms,hms,默认hms
|
| initialTimerDuration | 初始化时间 |
| minuteInterval | 分钟间隔 |
| secondInterval | 秒钟间隔 |
| alignment | 对齐方式 |
| backgroundColor | 背景色 |
| onTimerDurationChanged | @required ValueChanged<Duration> onTimerDurationChanged,选中时间变化回调 |
4. CupertinoTimerPicker 实例
示例1 CupertinoTimerPickerMode.hms
final cupertinoTimerPicker = CupertinoTimerPicker(
mode: CupertinoTimerPickerMode.hms, // 时间选择器模式
initialTimerDuration: Duration(hours: 1), // 初始化时间
minuteInterval: 5, // 分钟间隔
secondInterval: 20, // 秒钟间隔
alignment: Alignment.center, // 对齐方式
backgroundColor: Colors.white, // 背景色
// 选中时间变化回调
onTimerDurationChanged: (dur) {
chooseDuration = dur;
},
);
image.png
示例2 CupertinoTimerPickerMode.ms
final cupertinoTimerPicker = CupertinoTimerPicker(
mode: CupertinoTimerPickerMode.ms, // 时间选择器模式
initialTimerDuration: Duration(minutes: 10), // 初始化时间
minuteInterval: 5, // 分钟间隔
secondInterval: 20, // 秒钟间隔
alignment: Alignment.center, // 对齐方式
backgroundColor: Colors.white, // 背景色
// 选中时间变化回调
onTimerDurationChanged: (dur) {
chooseDuration = dur;
},
);
image.png
示例3 CupertinoTimerPickerMode.hm
final cupertinoTimerPicker = CupertinoTimerPicker(
mode: CupertinoTimerPickerMode.hm, // 时间选择器模式

minuteInterval: 5, // 分钟间隔
secondInterval: 20, // 秒钟间隔
alignment: Alignment.center, // 对齐方式
backgroundColor: Colors.white, // 背景色
