Hi, I have a question about this file. In the images of the readme it shows the player with a slider, but here in the code when running I don't see it. Were there changes?

Future and Streams are implemented in dart:core package is automatically imported in all the dart files.

This is the error its giving me
Launching lib\main.dart on TECNO CA6 in debug mode...
Running Gradle task 'assembleDebug'...

Getting "no posts" on home screen and nothing else(not section and anything) when running the code on Android emulator. Is there anything that needs to be changes for it to run as per the state mentioned in screenshots?
