Fix Typescript Errors

[flyingcircle]

I have recently converted all of the code to typescript. It should still compile just fine, but it would be nice to have the demo app be a good check on the correctness of the developer experience of using the library.

There are a lot of hanging typescript errors. This would be to go through and fix them so that tsc passes cleanly.

I would like to take up this, and fix the issues.

[khushal87]

@flyingcircle Can you assign me this issue?

[khushal87]

The rest of the issues are coming up from the package react-native-elements therefore this can be closed. @flyingcircle

[flyingcircle]

I'd prefer this stay open. If there's an issue showing up here, then we need a ticket written in RNE for it to be solved.

[khushal87]

The ticket is already there. I am working on the potential fixes of the same in the package. Reference - react-native-elements/react-native-elements#2870 @flyingcircle

[flyingcircle]

Great. Let's keep the ticket open here so that when it's done, we can validate that it's fixed here before closing.

[khushal87]

Yes. @flyingcircle

[khushal87]

I will try to handle the strict mode issues too soon. @flyingcircle Can I do so?
