Handling Results

Getting Results

Text Values

To get values of text fields, invoke the textFieldValueByType method with the required arguments:

Argument	Compulsory/optional	Description
`fieldType`	Compulsory	The field logical type, one of the `FieldType` values. The enumeration contains identifiers determining the logical type of the text data obtained while reading MRZ, document filling fields, and barcodes.
`lcid`	Optional	The ID of language-culture to differentiate one field of the same type from another. Contains the `LCID` enumeration value.
`source`	Optional	Identifies the zone from which data should be extracted. Contains the `ResultType` enumeration value.
`original`	Optional	Checks which value to extract: modified or original.

Dart

// Get surname
var surname = await results.textFieldValueByTypeLcidSourceOriginal(FieldType.SURNAME, LCID.INDONESIAN, ResultType.VISUAL_OCR_EXTENDED, true);
// Get address
var address = await results.textFieldValueByTypeLcidSourceOriginal(FieldType.ADDRESS, LCID.LATIN, ResultType.BAR_CODES_TEXT_DATA, true);

You can also go through all instances of text fields and get the required information, for example:

Dart

for (var textField in results.textResult!.fields) {
  for (var value in textField.values) {
    print(textField.fieldName +
        ', value: ' +
        (value.value ?? "null") +
        ', source: ' +
        value.sourceType.toString());
  }
}

Graphic Values

To get values of graphic fields, invoke the graphicFieldImageByType method with the required arguments:

Argument	Compulsory/optional	Description
`fieldType`	Compulsory	The field logical type, one of the `GraphicFieldType` values. The enumeration contains identifiers determining the logical type of the graphic data obtained while reading the document filling fields or barcodes.
`source`	Optional	Identifies the zone from which data should be extracted. The `ResultType` enumeration contains possible values.
`pageIndex`	Optional	The index of the document page from which the result is received.
`light`	Optional	The light type, one of the `Lights` values. The enumeration contains a set of identifiers used for identifying the document reader possibilities, specifying lighting schemes for scanning, etc.

Dart

// Get document image from the first page with white light
await results.graphicFieldImageByTypeSourcePageIndexLight (GraphicFieldType.DOCUMENT_IMAGE, ResultType.RAW_IMAGE, 0, Lights.WHITE_FULL);
// Get document image from the first page with UV light
await results.graphicFieldImageByTypeSourcePageIndexLight(GraphicFieldType.DOCUMENT_IMAGE, ResultType.RAW_IMAGE, 0,Lights.UV);
