More Output property in a Power Apps Component
Creating an output property in a Power Apps Component is a way for the component to provide data back to its parent. Output properties are defined with the @Output decorator, which takes an argument that specifies the name of the property. The value of this property can be set by assigning it within the component class, and will be available on the parent when calling “this.childComponent” (where childComponent is replaced with whatever your component instance is called).
When creating an output property, you must also create an event emitter that will emit events whenever you want to update its value. This event emitter should have a type corresponding to what type of data you expect as input from your parent - for example, if you're expecting strings as input from your parent then your event emitter's type should be string. You can then use this event emitter in combination with one or more methods in order to update its value and thus trigger changes on your parent when appropriate.
