问题描述
我希望用户选择日期和时间,因为有日期时间选择器对话框.
但是,有没有办法,我可以在某些Flutter小部件上持续显示日期时间,并像其他任何小部件一样使用?
容器(子:showTimePicker(上下文:上下文,initialTime:TimeOfDay.now(),builder:(BuildContext上下文,Widget子项){返回主题(数据:ThemeData.dark(),孩子:孩子,);},);}
但我不能将 showTimePicker
用作窗口小部件.
如何将 showTimePicker()
用作窗口小部件?以便可以在其顶部构建其他小部件.
就像您前一段时间一样,我遇到了问题,我复制了源代码并制作了自定义小部件.现在,它可以像任何小部件一样使用.如果您想采用此方法,我想提几件事.
- 我不确定这是否适用于本地化,我没有对此进行测试.
- 我不确定这是否可以用于浅色主题以外的其他主题,我仅在浅色主题上进行了测试.
您可以在此处找到代码. https://gist.github.com/mithunadhikari40/b55b9990ebc15d0d8bf70fd3f87709b>
用法:从上面的链接复制代码,创建一个dart文件,粘贴代码并按以下方式使用它:
SizedBox(子:TimePickerDialog(initialTime:TimeOfDay.fromDateTime(DateTime.now()),onTimeChange:(TimeOfDay时间){打印(我们得到的时间价值现在是$ time");},),),
I want the user to pick the date and time, for that there is date time picker dialogue.
Container(
child: showTimePicker(
context: context,
initialTime: TimeOfDay.now(),
builder: (BuildContext context, Widget child) {
return Theme(
data: ThemeData.dark(),
child: child,
);
},
);
}
but I cannot use showTimePicker
as Widget.
How to use showTimePicker()
as widget? so that other widgets can be built on top of it.
- I am not sure if this works well with localization, I did not test that.
- I am not sure if this works on other themes than the light theme, I only tested on the light theme.
You can find the code here.https://gist.github.com/mithunadhikari40/b55b9990ebc15d0d8bf70fd3f87709b0
Usage:Copy the code from the above link, create a dart file, paste the code and use it like this:
SizedBox(
child: TimePickerDialog(
initialTime: TimeOfDay.fromDateTime(DateTime.now()),
onTimeChange: (TimeOfDay time) {
print(
"What we get the value of the time is now $time");
},
),
),
