Improve cold boot time about social-app HOT 3 CLOSED

Great work @joaoferreiro. I agree with your conclusion.

After assigning this to you, I noticed that cold boot had seemed to improve, and I believe it was possibly due to some dropped dependencies (reanimated and a gestures library) but I didn't look more deeply. I figured I'd keep you on this task so we could have access to the code and confirm the results.

Go ahead and upload the branch as code-split and then leave it there. We'll retain it as a reference in case future cold boot times worsen.

  • With the exception of Login screen and MobileShell, Menu and TabSelector components
• Results:
  • No visible improvement between the older version and the newest, using react-native-blunder-splitter

@pfrazee will research a bit more on how can we improve this stat tomorrow. Then I would suggest we connect to discuss next steps on this

@pfrazee just added react-native-bundle-splitter's to all the components on the src/view folder (despite only src/view/screens) and the results are no different: no improvement on cold start time.

Besides this, using this library would require us to change a lot of the folder structure that we currently have. Example:

To conclude, unless we've received any comments on this I don't believe this is a major issue.
The cold-start time of the release version on an iPhone 7 is < 2sec. I've tested other social networks on an iPhone 8 and it's 3 to 5 sec. This makes me believe that we could drop this. Lmk what you think about it
