hello.
This time, Firebase version 9 has been released.
A student told me that there were a lot of changes in grammar in version 9.
I have uploaded the modified source code for version 9.
The changes are a modification to make the app faster by greatly reducing the application size through modularization.
From the perspective of writing source code,
Since this is a change in grammar, not a change in logic, those who are taking the lecture for the first time can follow the lecture in order.
And I will record and upload a lecture where I will change the current source code to the source code that matches version 9 as soon as possible.
Thank you so much for always watching my lectures.
