TypeSelector<T> class

A TypeSelector widget to usage for select one in yours available options.

The type parameter T serves the same purpose as that of the TypeSelector class' type parameter. The TypeSelector requests a callback Function(T) named as onValueChanged which will be triggered after the value changed.

If the options list is absent, an assertion error will be throw.

assert(options != null);

If the onValueChanged function is absent, an assertion error will be throw.

assert(onValueChanged != null);

Constructors

TypeSelector({required List<T> options, bool multiple = false, dynamic value, dynamic onValueChanged, dynamic values, dynamic onValuesChanged, dynamic maxQuantityValues, dynamic onMaxQuantityValues, Duration transitionDuration = const Duration(milliseconds: 250), EdgeInsets contentPadding = const EdgeInsets.all(8.0), TextOverflow valueLabelOverflow = TextOverflow.clip, bool toggleOptionOnTap = false, double separatorWidth = 2.0, double height = 50.0, double? optionWidth, String setValueLabel(T value)?, TextStyle? valueLabelStyle, Color? activeColor, Color? disabledColor, dynamic comparingBy(T value)?})
The default TypeSelector constructor that render a rounded corner TypeSelector.
TypeSelector.rect({required List<T> options, bool multiple = false, dynamic value, dynamic onValueChanged, dynamic values, dynamic onValuesChanged, dynamic maxQuantityValues, dynamic onMaxQuantityValues, Duration transitionDuration = const Duration(milliseconds: 250), EdgeInsets contentPadding = const EdgeInsets.all(8.0), TextOverflow valueLabelOverflow = TextOverflow.clip, bool toggleOptionOnTap = false, double separatorWidth = 2.0, double height = 50.0, double? optionWidth, String setValueLabel(T value)?, TextStyle? valueLabelStyle, Color? activeColor, Color? disabledColor, dynamic comparingBy(T value)?})
The default TypeSelector constructor that render a rect corner TypeSelector.

Properties

activeColor → Color?
The active Color of the TypeSelector. Is displayed when an option is selected. The default value is:
final
comparingBy → (dynamic Function(T value)?)
The default comparation for obtain selected value uses the == operator. But when working with objects, this method don't will work properly. Using this function, it's possible set how the comparation supose to be. Example of usage:
final
contentPadding → EdgeInsets
The padding for the TypeSelector. The default value is:
final
disabledColor → Color?
The disabled Color of the TypeSelector. Is displayed when an option is not selected. The default value is:
final
hashCode → int
The hash code for this object.
no setterinherited
height → double
The height for TypeSelector.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxQuantityValues → int?
The maxQuantityValues for this TypeSelector (when multiple attribute is true).
final
multiple → bool
Defines value of TypeSelector is a single or multiple objects. The default value is:
final
onMaxQuantityValues → (void Function(int maxQuantityValues)?)
The Callback function called when values.length == maxQuantityValues.
final
onValueChanged → ValueChanged<T?>?
The callback function reference that is called after the TypeSelector value changes. Triggered when the value is changed.
final
onValuesChanged → ValueChanged<List<T>>?
The callback function reference that is called after the TypeSelector values changes. Triggered when the values is changed.
final
options → List<T>
The available options for TypeSelector.
final
optionWidth → double?
The width for the each option (from options).
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
separatorWidth → double
The separator width for options.
final
setValueLabel → (String Function(T value)?)
This function defines a label for every option (from options). The default value is value. Example of usage:
final
toggleOptionOnTap → bool
If this value is set to true, on tap in the current selected option the value is set to null.
final
transitionDuration → Duration
The transitionDuration of the TypeSelector animation on value changed. The default value is:
final
value → T?
The value for this TypeSelector.
final
valueLabelOverflow → TextOverflow
The overflow mode when the label is overflowing the optionWidth. The default value is:
final
valueLabelStyle → TextStyle?
The style for the value label. The default value is:
final
values ↔ List<T>?
The values for this TypeSelector (when multiple attribute is true).
