Add widget unmount lifecycle method #766
Description
Enhancement
Currently, there doesn't appear to be a way to tie into the widget lifecycle for when a widget is unmounted. This can be useful for cleanup activities that should occur, such as cleaning up event listeners (that can't be replaced with property callbacks) when a widget is unloaded.
Package Version: 0.1.2
Code
class Widget extends WidgetBase {
constructor() {
super();
global.addEventListener('message', this.doSomething);
}
doSomething: () => {};
// There's currently not a place to cleanup this event listener
}Expected behavior:
class Widget extends WidgetBase {
constructor() {
super();
global.addEventListener('message', this.doSomething);
}
doSomething: () => {};
onUmount() {
global.removeEventListener('message', this.doSomething);
}
}Actual behavior:
There currently doesn't seem to be a hook into the lifecycle to accomplish this.
