Struct ButtonGroupAction 

pub struct ButtonGroupAction<State: 'static> { /* private fields */ }

A declarative description of one member — M3EButtonGroupAction (models/m3e_button_group_action.dart:12).

Built with button_group_action (labelled) or button_group_icon_action (icon-only); the reference’s icon != null || label != null assertion is a constructor choice here rather than a runtime check.

Implementations

impl<State: 'static> ButtonGroupAction<State>

pub fn icon<F: Fn() -> AnyView<State> + 'static>(self, icon: F) -> Self

The icon shown while unchecked (and while checked too, unless Self::checked_icon is set).

pub fn checked_icon<F: Fn() -> AnyView<State> + 'static>(self, icon: F) -> Self

The icon shown while checked. Falls back to Self::icon when unset.

pub fn label(self, label: impl Into<String>) -> Self

The label shown while unchecked (and while checked too, unless Self::checked_label is set).

pub fn checked_label(self, label: impl Into<String>) -> Self

The label shown while checked. Falls back to Self::label when unset.

pub fn checked(self, checked: bool) -> Self

The uncontrolled checked flag: consulted only when the group wires neither a selected index nor a selected-index set (the third arm of _resolveToggleActionSelected).

pub fn enabled(self, enabled: bool) -> Self

Whether this member accepts a press (M3EButtonGroupAction.enabled).

pub fn width(self, width: f64) -> Self

Pin this member’s main-axis extent instead of letting it size to its content (M3EButtonGroupAction.width).
