Feature/771 ios onstyleready reliability

[AAverin]

Looking into report in #771, this PR applies proposed by @felix-ht change to improve onStyleReadyCallback reliability on iOS

[felix-ht]

Does this also fix the original issue you were seeing?

Saw your other comment on #771 - LGTM

[AAverin]

@felix-ht Do you know if there is anything I should do for builds to pass?

[felix-ht]

@AAverin no idea seems to be failing for all buids atm

[m0nac0]

Regarding the build failure: I've encountered something similar in the past, and I'm nearly certain it's because of a malformed .netrc file. Maybe the SDK_REGISTRY_TOKEN is not found and therefore empty?
That would explain the error: the netrc file ends unexpectedly after "password" without any actual password.

@m0nac0 .netrc is only used on iOS but Android also seems to fail. Probably some mistake in CI configuration

[AAverin]

@tobrun Could you please take a look at what is in Settings => Secrets? Might be ANDROID_CI_DOWNLOADS_TOKEN property is not set

[m0nac0]

@m0nac0 .netrc is only used on iOS but Android also seems to fail. Probably some mistake in CI configuration

Right. That message is even clearer regarding the missing SDK_REGISTRY_TOKEN

[tobrun]

Confirmed in #783 through github action run that the token is not shared to PRs coming from forks. This doesn't seem configurable, I will try finding a solution for it.

This all said, if you are part of the @flutter-mapbox-gl/team, please use a direct clone of the repo instead of forking.
Most of the PRs do come from this select group :)
