contains method

  1. @override
bool contains(
  1. String key
)
override

Checks whether the key exists in the storage. key Key to check. Returns true if a value is stored under the key (regardless of type).

Example:

// Check if keys exist
bool hasUserName = _userStorage!.contains("user_name");
bool hasNonExistent = _userStorage!.contains("non_existent_key");
print("Contains 'user_name': $hasUserName");
print("Contains 'non_existent_key': $hasNonExistent");

Implementation

@override
bool contains(String key) {
    final _containsFfi = __lib.catchArgumentError(() => __lib.nativeLibrary.lookupFunction<
        Uint8 Function(Pointer<Void>, Pointer<Void>),
        int Function(Pointer<Void>, Pointer<Void>)
      >('navigine_sdk_flutter_KeyValueStorage_contains__Key'));
    final _keyHandle = navigine_sdk_flutter_String_ToFfi(key);
    final _handle = this.handle;
    final __resultHandle = _containsFfi(_handle, _keyHandle);
    navigine_sdk_flutter_String_ReleaseFfiHandle(_keyHandle);
    final _result = navigine_sdk_flutter_bool_FromFfi(__resultHandle);
    navigine_sdk_flutter_bool_ReleaseFfiHandle(__resultHandle);
    return _result;
}
