String parsing (using FlutterConfig.get()) leaves extra quote characters on iOS devices

[BirdSamuel]

NOTE: This is not all iOS devices. I haven't been able to pin down which specific devices/versions have this issue.
Both using the same code from this repository: https://github.com/BirdSamuel/test_flutter_config
The .env file specifically: https://github.com/BirdSamuel/test_flutter_config/blob/main/.env

When pulling strings from a .env file, some entries with quotation marks bring over the quotes on iOS devices. This example shows everything but the last entry.

Android Emulator example, also tested using Samsung Galaxy S21 Ultra

iOS example (using iPhone XS Max), also got the same result with iOS Simulator with iPhone SE - 3rd generation - iOS 15.5
NOTE: The last entry (being the EXAMPLE_URL) did not carry the quote over. Maybe is a clue into the fix.
