Configures the SDK to use a least-recently-used garbage collector for memory cache.
Once configured, the SDK will attempt to remove documents that are least recently used in
batches, if the current cache size is larger than the given target cache size. Default cache size
is 100MB.
To use, create an instance using one of the initializers, then initialize
MemoryCacheSettings with this instance.
Creates an instance of FIRMemoryLRUGCSettings, with default target cache size 100MB. The SDK
will run garbage collection if the current cache size is larger than 100MB.
Creates an instance of FIRMemoryLRUGCSettings, with a custom target cache size. The SDK will
run garbage collection if the current cache size is larger than the given size.
