Extract Data from PDF Form Fields in Flutter
PSPDFKit for Flutter allows you to extract data from form fields programmatically. Each form field has a fully qualified name, which is used to identify and retrieve a specific form field object before extracting its data.
Obtaining the Fully Qualified Name of a Form Field
The example below shows how to obtain the fully qualified name of the first form field on the first page of a document:
dynamic allAnnotations = await Pspdfkit.getAnnotations(0, 'all'); // Get the fully qualified name for the first form field. String? formFieldName = (allAnnotations['formFieldName']);
Getting the Data from a Form Field
The example below shows how to get the data from a form field with the fully qualified name,
// Get the data from a form field with the fully qualified name, `formFieldName`. String? lastName = await Pspdfkit.getFormFieldValue('formFieldName');
