Is possible to re-set the value of firebase list?


I’m trying to change the value of firebase list that defined in app.ts after few time.

For some reason I need to put the list in app.ts but I couldn’t change its value any more?

Maybe my way is wrong but is there any possible ways to defined firebase list to be used in whole app and I can to edit this list at any time ?

I solved this issue using call functions to un/subscribe items
