fixes #96 #100

[ncdm-stldr]

There are reports of a crash happening with newer versions of flutter (issues #96 and #100).
This pull request aims to solve the crash.

Explanation of the changes:

• The renderer.close() in getPage sometimes creates an exception. It is because the close is already preformed by the try-catch clause itself. The code renderer.close() can therefore be safely removed.
• A else block has been added because it was missing (e.g. result should not been used twice).

@lohanidamodar would it be possible to get this merged and released to pub.dev? The code is simple and seems sound

It works fine with that version but as soon as i publish my app in release mode it crashes when trying to access cloud_firestore.
Seems to me that this package uses too old versions of certain dependencies.
