KivyMD callback(self,instance) example

Question

I am using a floating action button speed dial in kivymd. I have added the data dictionary and want to add separate functions to all the sub buttons. For that I have to use callback. Can anyone tell me by an example how do I do it?
Kv code:

MDFloatingActionButtonSpeedDial:
    callback: app.callback
    data:app.data

Python code:

class Example(MDApp):
    data = {
        'language-python': 'Python',
        'language-php': 'PHP',
        'language-cpp': 'C++',
    }

    def build(self):
        return Builder.load_string(KV)

Update
I followed up and found that callback:app.callback will be required to call the function.

According to the documentation, you can just add a callback method to your App, like this:

class Example(MDApp):
    data = {
        'language-python': 'Python',
        'language-php': 'PHP',
        'language-cpp': 'C++',
    }

    def build(self):
        return Builder.load_string(KV)

    def callback(self, instance):
        print(instance.icon)
