Hello. your videos helped me a lot. thanks for the contribution, any suggestion to validate user to mysql and interact with the DB, thanks

Thank you for this great tutorial. I have a question. How can I covert this code from Functional Components to React Class Components ?
data and SetData are pretty different in the case of a Class component. can you provide your code in class component ?
Functional componentes are faster, if you want to manage state then you should use useState(or useMemo etc...)
Need a Video of Back handler after login
for eg: user gets navigated to the login screen when pressing the back button of the android device
you are a life saver! Thank you!
