YaruRadio<T> class

A Yaru radio.

Used to select between a number of mutually exclusive values. When one radio button in a group is selected, the other radio buttons in the group cease to be selected. The values are of type T, the type parameter of the YaruRadio class. Enums are commonly used for this purpose.

The radio button itself does not maintain any state. Instead, selecting the radio invokes the onChanged callback, passing value as a parameter. If groupValue and value match, this radio will be selected. Most widgets will respond to onChanged by calling State.setState to update the radio button's groupValue.

Properties

autofocus → bool
True if this widget will be selected as the initial focus when no other node in its scope is currently focused.
final
checked → bool
Getter used to link T to a bool value. If true, the YaruTogglable will be considered as checked.
no setter
checkmarkColor → Color?
The color to use for the checkmark when this radio is checked.
final
focusNode → FocusNode?
An optional focus node to use as the focus node for this widget.
final
groupValue → T?
The currently selected value for a group of radio buttons.
final
hashCode → int
The hash code for this object.
no setterinherited
interactive → bool
Determine if this YaruTogglable can handle events.
no setter
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mouseCursor → MouseCursor?
The cursor for a mouse pointer when it enters or is hovering over the widget.
final
onChanged → ValueChanged<T?>?
Called when the user selects this radio button.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selectedColor → Color?
The color to use when this radio is checked.
final
statesController → WidgetStatesController?
Controls the states of the YaruTogglable.
final
toggleable → bool
Set to true if this radio button is allowed to be returned to an indeterminate state by selecting it again when selected.
final
tristate → bool
By default, a YaruTogglable widget can only handle two state. If true, it will be able to display tree values.
no setter
value → T
The value represented by this radio button.
