Fix syntax errors in getting started example at the end

[gewenyu99]

This fixes errors for Android and Flutter.

For Android:

• Fixes the use of single quotes for strings

For Flutter

• Missing semicolon
• Use of triple equal sign ===, which is no longer supported.

@gewenyu99 I noticed there are more instances in the same file where we're using single quotes for strings in kotlin. Please fix those as well.

Also take a look at the entire flutter file too

The Android/Kotlin examples should also use == (structural equality) instead of === (referential equality) for these cases

Addressed. Fixed all === usages and added ; where applicable

Replaced with structural equality :)
