How to implement WebDriver Event Listeners in Robot Framework

I'm new to Robot Framework. I'm trying to implement WebDriver Event Listeners by importing Selenium Library.

In my Test case, I have this import

Library             SeleniumLibrary    event_firing_webdriver=${CURDIR}/RobotFrameworkListener.py

In RobotFrameworkListener.py file,

    from robot.api import logger
    from selenium.webdriver.support.events import AbstractEventListener
    from robot.libraries.BuiltIn import BuiltIn
    from selenium.webdriver.support.events import EventFiringWebDriver

    selib = BuiltIn().get_library_instance("SeleniumLibrary")
    driver = selib.driver
            
    class RobotFrameworkListener(AbstractEventListener):
         def before_navigate_to(self, url, driver):
             logger.info("URL before navigation: '%s'." % url)
         def after_navigate_to(self, url, driver):
             logger.info("URL after navigation: '%s'." % driver.current_url)
         def before_change_value_of(self, element, driver):
             dict= element.get_property('attributes')
             element_value = dict[2]['value']
             logger.info("Before clearing/entering the text field '%s'." % element_value)
         def after_change_value_of(self, element, driver):
             dict= element.get_property('attributes')
             element_value = dict[2]['value']
             logger.info("After clearing/entering the text field '%s'." % element_value)

So could some one help me on how to trigger listeners for my main Test case so that I can do an action on web driver events like after click, before click, after entering the text etc? Let me know if there is any other way to do it :) Thanks in advance!

I commented some lines in your listener, and it worked:

RobotFrameworkListener.py file:

from robot.api import logger
from selenium.webdriver.support.events import AbstractEventListener
from robot.libraries.BuiltIn import BuiltIn
# from selenium.webdriver.support.events import EventFiringWebDriver

# selib = BuiltIn().get_library_instance("SeleniumLibrary")
# driver = selib.driver
        
class RobotFrameworkListener(AbstractEventListener):
    def before_navigate_to(self, url, driver):
        logger.info("URL before navigation: '%s'." % url)

    def after_navigate_to(self, url, driver):
         logger.info("URL after navigation: '%s'." % driver.current_url)
    
    def before_change_value_of(self, element, driver):
        dict= element.get_property('attributes')
        element_value = dict[2]['value']
        logger.info("Before clearing/entering the text field '%s'." % element_value)
    
    def after_change_value_of(self, element, driver):
        dict= element.get_property('attributes')
        element_value = dict[2]['value']
        logger.info("After clearing/entering the text field '%s'." % element_value)
