enterText function

Future<InputResult> enterText(InputInput input)

Enters text into a field in the running Flutter app.

If no selector flags are provided, targets the focused field. Never throws; all error conditions are represented as sealed result cases.

Implementation

Future<InputResult> enterText(InputInput input) async {
  try {
    final isolateId = await checkFdbHelper();
    if (isolateId == null) return const InputNoFdbHelper();

    final params = <String, dynamic>{
      'isolateId': isolateId,
      'input': input.textToEnter,
    };

    final hasSelector = input.text != null || input.key != null || input.type != null;
    if (!hasSelector) {
      params['focused'] = 'true';
    }
    if (input.text != null) params['text'] = input.text;
    if (input.key != null) params['key'] = input.key;
    if (input.type != null) params['type'] = input.type;
    if (input.index != null) params['index'] = input.index.toString();

    final result = await fdbEnterText(params);

    if (result.isSuccess) {
      final fieldType = result.widgetType ?? input.type ?? 'field';
      return InputSuccess(fieldType: fieldType, value: input.textToEnter);
    }

    if (result.error != null) return InputRelayedError(result.error!);

    return InputUnexpectedResponse(result.unexpected);
  } on AppDiedException catch (e) {
    return InputAppDied(logLines: e.logLines, reason: e.reason);
  } catch (e) {
    return InputError(e.toString());
  }
}
