Dependent flags

[dabeeeenster]

Flags being dependent on other flags has been requested several times.

One option for this would be to allow flag booleans/values to be used as segment operator values. So for example, if you wanted Flag B to only be enabled if Flag A is enabled:

• Create Flag A. Set as disabled.
• Create Flag B. Set as disabled.
• Create Segment. Single Rule: If Value of Flag A is set.
• Set a segment override on Flag B: If Segment set, override Flag B value to true.

Cross-Project dependencies

We often get asked "Can we have a project with shared flags and a project with specific flags for e.g. iOS that combines both sets of flags". We could achieve this functionality with cross-project dependencies. Eg:

• Create a shared project and a flag my_flag_1
• Create an Android project
• Create an iOS project
• Create a flag in iOS and one in Android, my_flag_1 and make it dependent on the shared project flag.

We've talked about this here but maybe the above solution would be sufficient

Will this function like a keystone flag? If Flag A is enabled I can also enabled Flag B-F?

Sorry I'm not clear what you mean here?

[landonjs]

From your example in the description will I be able to set the value of one flag based on another flag. Will I be able to set the value of multiple flags based on Flag A?

That would get me close to something like this: https://martinfowler.com/bliki/KeystoneInterface.html

Yes that is what this would achieve.
