Changes

SDK Status

Flagship SDK statuses have been renamed or changed:

4.X	3.X	Description
NOT_INITIALIZED	NOT__INITIALIZED	Flagship SDK has not been started or initialized successfully.
INITIALIZING	STARTING	Flagship SDK is initializing.
INITIALIZING	POLLING	Flagship SDK has been started successfully but is still polling campaigns.
PANIC	PANIC	Flagship SDK is ready but is running in Panic mode: All features are disabled except the one which refresh this status.
INITIALIZED	READY	Flagship SDK is ready to use.

Flagship status listener have been renamed accordingly:

val config = FlagshipConfig.Bucketing()
	.withFlagshipStatusListener { flagshipStatus ->
    //use status
  })

val config = FlagshipConfig.Bucketing()
	.withFlagshipStatusListener { flagshipStatus ->
    //use status
  })

Visitor consent

The Flagship newVisitor method now takes consent as mandatory parameter.

Example:

 val visitor = Flagship.newVisitor("visitor_id", true).build()

 val visitor = Flagship.newVisitor("visitor_id").build()

Get flag value

In version 4.X, the approach to setting a flag's default value has been modified. The default value is no longer set using the getFlag method of visitor instance. Instead, it is now set using the getValue of flag instance.

val flag = fsVisitor.getFlag("myFlagKey")
val flagValue = flag.value("myDefaultValue")

val flag = fsVisitor.getFlag("myFlagKey", "myDefaultValue")
val flagValue = flag.value()
