[firebase_remote_config] Should Flutter firebase-remote-config be updated mandatorily?

[XinyueZ]

Hello, we get an email from Firebase, we see the version update is required for the native version, shall we do it as well for the Flutter version?

We are writing to remind you that we are deprecating older versions of the Android and iOS Remote Config SDK. After May 2, 2021, these SDKs will no longer be supported and will not be able to fetch from Remote Config.

What happened?
In order to streamline Remote Config and offer new features, we will be turning down the legacy API these older SDKs depend on.

What’s next?
To continue using Remote Config, be sure to upgrade your apps to SDK version 16.3.0+ for Android and 6.3.0+ for iOS before May 2, 2021. Once this date has passed, your app will no longer be able to fetch values from Remote Config and will fall back to the last fetched values or the default values within your app.

Thank you
