File Import

If your simple goal is to import image files and generate a non-searchable (includes no text) PDF file from it, use the DocutainSdkDocument class.

try {
    bool rcImport =
        await DocutainSdkDocument.loadFile(filePath);
    if (!rcImport) {
        //an error occured
        var error = await DocutainSdk.getLastError();
    } else {
        //generate a PDF from the imported file
        File? pdfFile = await DocutainSdkDocument.writePDF(
            path, 'SamplePDF');
    }
} on PlatformException catch (exception) {
    if (exception.code == "SecurityException") {
        //file is encrypted and password was wrong or empty
        //provide the correct password in the loadFile() method
    }
}

If you want to create a searchable PDF (includes text), or get the detected data or text of the imported file, use the DocutainSdkDocumentDataReader class.

try {
    bool rcImport =
        await DocutainSdkDocumentDataReader.loadFile(filePath);
    if (!rcImport) {
        //an error occured
        var error = await DocutainSdk.getLastError();
    } else {
        //generate a searchable PDF from the imported file
        File? pdfFile = await DocutainSdkDocument.writePDF(
            path, 'SamplePDF');
        //get the detected text 
        final text =
            await DocutainSdkDocumentDataReader.getText();
        //get the detected data
        final data =
            await DocutainSdkDocumentDataReader.analyze();
    }
} on PlatformException catch (exception) {
    if (exception.code == "SecurityException") {
        //file is encrypted and password was wrong or empty
        //provide the correct password in the loadFile() method
    }
}
