After overriding three lifecycle methods of WebComponent
: created()
, inserted()
, and removed()
, I can see that the first two are called consistently but removed()
is never called. Is there anything special that needs to be done so that removed()
is called? Or is it simply never called?
Is WebComponent.removed() ever called?

The
removed()
method is called when a custom element is removed from the DOM. Here is a small program that demonstrates the use of thecreated()
,inserted()
, andremoved()
lifecycle events.Create a Dart web application with an
index.html
file that looks like this:This file imports and displays a custom element,
<my-element>
.Define the following file that defines
<my-element>
:And define the accompanying Dart file that demonstrates the lifecycle methods getting called:
When you run
index.html
, you will see a paragraph with some text in it. Thecreated()
andinserted()
lifecycle methods are called, and 'created' and 'inserted' messages print in the console. When you click on the div that contains the custom element, the element is removed, theremoved()
lifecycle method is called, and 'removed' prints in the console.Hope this helps.
