Ionic 6.4 introduces key improvements to the framework's modal, toast, and toggle functionalities, enhancing developers' control over user interactions. The update refines the canDismiss feature in modals by incorporating role and data parameters into the callback, allowing more precise conditions for dismissing modals. Toasts now benefit from a globally configurable default duration, thanks to the new toastDuration setting, while toggles gain a customizable global option for on/off labels through the toggleOnOffLabels configuration. These enhancements aim to provide developers with greater flexibility and customization capabilities, and the Ionic team expresses gratitude to contributors and looks forward to further advancements in 2023.
