Hello everybody!

A lot of people read my last post about my group_button package
And I decide to tell you about huge package update to 5.0.0 version.

The main feature of the update - go to Generics

Changelog:

🔥 MAIN FEAT: GroupButton<T> now is generic class.
Now you can create int, DateTime, double or YourCustomClass typed buttons List for default GroupButton constructor.

❗️ BREAKING: All deprecated by 4.3.0 and 4.6.0 fields was removed from package.
More here
❗️ BREAKING: buttonBuilder from 4.6.0 now build buttons by value
The buttonIndexedBuilder took over the past functionality of the buttonBuilder
⬆️ FEAT: onSelected method now calling with value argument.
More here
🎀 INFO: Updated examples & README

What is thats meaning ?

In new 5.0.0 version you can set custom buttons value type
It can be int, DateTime, double or YourCustomClass
Button text will be result of .toString() model method in common button display case

GroupButton<DateTime>(
  buttons: [DateTime(2022, 4, 9), DateTime(2022, 4, 10)],
)

Also you can use generic button values with custom buttonBuilder
In order to turn values into any widget

GroupButton<DateTime>(
  buttons: [DateTime(2022, 4, 9), DateTime(2022, 4, 10)],
  buttonBuilder: (selected, date, context) {
    return Text('${date.year}-${date.month}-${date.day}');
  },
),

Customization

In order to customize your buttons inside GroupButton you can use GroupButtonOptions

GroupButtonOptions(
  selectedShadow: const [],
  selectedTextStyle: TextStyle(
    fontSize: 20,
    color: Colors.pink[900],
  ),
  selectedColor: Colors.pink[100],
  unselectedShadow: const [],
  unselectedColor: Colors.amber[100],
  unselectedTextStyle: TextStyle(
    fontSize: 20,
    color: Colors.amber[900],
  ),
  selectedBorderColor: Colors.pink[900],
  unselectedBorderColor: Colors.amber[900],
  borderRadius: BorderRadius.circular(100),
  spacing: 10,
  runSpacing: 10,
  groupingType: GroupingType.wrap,
  direction: Axis.horizontal,
  buttonHeight: 60,
  buttonWidth: 60,
  mainGroupAlignment: MainGroupAlignment.start,
  crossGroupAlignment: CrossGroupAlignment.start,
  groupRunAlignment: GroupRunAlignment.start,
  textAlign: TextAlign.center,
  textPadding: EdgeInsets.zero,
  alignment: Alignment.center,
  elevation: 0,
),

GroupButtonValueBuilder buttonBuilder

Custom builder method to create
your own custom buttons by button [T] value

final buttons = ['10:00', '11:00', '12:00'];

GroupButton(
  buttons: buttons,
  buttonBuilder: (selected, val, context) {
    return Text('$val is selected: $selected');
  },
),

And this example equals to next ->

GroupButtonIndexedBuilder buttonIndexedBuilder

Custom builder method to create
your own custom buttons by button [int] index

final buttons = ['10:00', '11:00', '12:00'];

GroupButton(
  buttons: buttons,
  buttonIndexedBuilder: (selected, index, context) {
    return Text('${buttons[index]} selected: $selected');
  },
),

Remove deprecated and refactor base

And last awesome chage is update package api
Now you can create group of buttons by 1 code line😳:

GroupButton(buttons: ['10:00', '11:00', '12:00', '13:00']),

GroupButton(buttons: [10.5, 11, 11.5, 12, 12.5]),

GroupButton(buttons: [35, 36, 37, 38, 39]),

GroupButton(buttons: [false, true]),
