# startTextDataScanner static method

Future<TextDataScanResult> startTextDataScanner(

1. TextDataScannerConfiguration config

)

Starts the TextData Scanner UI as full-screen modal UI dialog. The Text Data Scanner is a generic text recognizer and provides the ability to scan small text blocks. The UI contains a configurable finder (frame) within which the text to be scanned can be captured.

## Implementation

    static Future<TextDataScanResult> startTextDataScanner(
        TextDataScannerConfiguration config) async {
      try {
        var updatedParameters = config.toJson();
        const defaultJsonName = "TextDataScreen";
        var configuration = await SharedCalls.applyParametersOnDefaultJson(
            defaultJsonName, updatedParameters);
        var result = await SharedCalls.invoke(
            _channel, 'startTextDataScanner', configuration);
        if (SharedCalls.wasCanceled(result)) {
          return TextDataScanResult.canceled();
        }
        return TextDataScanResult.fromJson(jsonDecode(result));
      } catch (e) {
        Logger.root.severe(e);
        return TextDataScanResult.error(e.toString());
      }
    }
