Globals in Flutter States



Is it bad practice to use globals for state management in Flutter? I've come across a few different methodologies (ex: Redux) that seem like quite a bit of work to integrate with Firebase Cloud Firestore. Wondering what the downfalls would be to essentially manage my state with key value pairs using globals such as something like this:

PySpark count values by condition

Clash Royale CLAN TAG #URR8PPP PySpark count values by condition I have a DataFrame, a snippet here: [['u1', 1], ['u2', 0]] basically one string ('f') and either a 1 or a 0 for second element ('is_fav'). What I need to do is grouping on the first field and counting the occurrences of 1s and 0s. I was hoping to do something like num_fav = count((col("is_fav") == 1)).alias("num_fav") num_nonfav = count((col("is_fav") == 0)).alias("num_nonfav") df.groupBy("f").agg(num_fav, num_nonfav) It does not work properly, I get in both cases the same result which amounts to the count for the items in the group, so the filter (whether it is a 1 or a 0) seems to be ignored. Does this depend on how count works? count 1 Answer 1 There is no filter here.
