 GO Feature Flag supports different all OpenFeature supported types of feature flags, it means that you can use all the accessor directly
-- **Bool**: `client.getBooleanValue(key: "my-flag", defaultValue: false)`
-- **String**: `client.getStringValue(key: "my-flag", defaultValue: "default")`
-- **Integer**: `client.getIntegerValue(key: "my-flag", defaultValue: 1)`
-- **Double**: `client.getDoubleValue(key: "my-flag", defaultValue: 1.1)`
-- **Object**: `client.getObjectValue(key: "my-flag", defaultValue: Value.structure(["key":Value.integer("1234"))`
