How often you see buttons in applications🧐?
I think in every application that you seen in life.
And buttons are different
| Like that | Or like that | Or like that if your designer is stuck in the past |
|---|---|---|
 |
 |
 |
But all these buttons are often grouped together for some purposes.
| For multiselect forms | Select gender |
|---|---|
 |
 |
| For filters | Another selection |
 |
 |
And a lot of other cases...
And how to make similar widgets in Flutter ?
Flutter have base Radio widget for select one of all items logic.
It is very easy to use.
You need to tell the value of this element and the current selected value for the entire group
Column(
mainAxisAlignment: MainAxisAlignment.start,
children: [
ListTile(
title: Text("Male"),
leading: Radio(
value: 1,
groupValue: val,
onChanged: (value) {
setState(() {
val = value;
});
},
activeColor: Colors.green,
),
),
ListTile(
title: Text("Female"),
leading: Radio(
value: 2,
groupValue: val,
onChanged: (value) {
setState(() {
val = value;
});
},
activeColor: Colors.green,
),
),
],
)
For multiple choice we have a Checkbox.
Everything is not so simple with him, the work of several checkboxes still needs to be organized.
Checkbox(
value: false,
onChanged: (value) {
setState(() {
_value = value;
});
},
)
What if I don 't want to spend a lot of time releasing similar widgets with logic ?
Or maybe I want to make the widgets custom, not the default Radio or Checkbox ?
That's why I'm writing this post
I have created a library to creating the selection buttons in minimum of time.
For example - see how you can make a group of time selection buttons in 5 lines
GroupButton(
isRadio: false,
onSelected: (index, isSelected) => print('$index button is selected'),
buttons: ["12:00", "13:00", "14:30", "18:00", "19:00", "21:40", "22:00", "23:30"],
)
Here result:
Well, what if I want to use default checkboxes?
It will be very simple
- First we will put the buttons in a variable and create a controller
- After that we will add a buttonBuilder to build any of your most interesting button UI
- That's all ...
final _controller = GroupButtonController();
final _buttons = ["12:00", "13:00", "14:30", "18:00", "19:00", "21:40", "22:00", "23:30"];
GroupButton(
isRadio: false,
controller: _controller,
onSelected: (index, isSelected) =>
print('$index button is selected'),
buttons: _buttons,
buttonBuilder: (selected, i, context) => CheckBoxTile(
title: _buttons[i],
selected: selected,
onTap: () => _controller.toggleIndexes([i]),
),
),
Here result:
I could tell you a lot more about this package, but I think its repository will tell everything instead of me.

Support this project with an ⭐️asterisk on Github. It's not difficult, but it's very nice

Nice 💪🏼 thank you very much for that..
having not touch mobile dev for years, I would like to give Flutter a second chance during my spare times 😂😍
It 's definitely worth a try ! 👍
Nice.
❤️
I started Flutter some months back, it's interesting and this is nice
Thank you very much for the feedback
I'm MD—Shahadat Hossain from Bangladesh. I'm a fresher flutter developer. I can fetch data from the Rest API and Firebase as well. And I have MVVM architecture knowledge and I can make eye-catching UI designs. I'm committed and dedicated to my work and always learning something new.
Now I'd like to do a job or internship to increase my work ability and financial support.
Would you mind, if I got help from you about getting the opportunity to work on Flutter?
cool 😝
Thank you !
Really a detailed guide. Thanks.
