Get a NamespacedKey from the supplied string with a default namespace if a namespace is not defined. This is a utility method meant to fetch a NamespacedKey from user input. Please note that casing does matter and any instance of uppercase characters will be considered invalid. The input contract is as follows:

 fromString("foo", plugin) - > "plugin:foo"
 fromString("foo:bar", plugin) - > "foo:bar"
 fromString(":foo", null) - > "minecraft:foo"
 fromString("foo", null) - > "minecraft:foo"
 fromString("Foo", plugin) - > null
 fromString(":Foo", plugin) - > null
 fromString("foo:bar:bazz", plugin) - > null
 fromString("", plugin) - > null
 

Parameters:

string - the string to convert to a NamespacedKey

defaultNamespace - the default namespace to use if none was supplied. If null, the minecraft namespace (minecraft(String)) will be used

Returns:

the created NamespacedKey. null if invalid key
