Flatten PDF forms in Flutter

Markdown version of this page, suitable for AI agents and automation

Nutrient Flutter SDK enables you to create a new document with flattened forms. In a document with flattened forms, the form fields and their contents remain visible, but users can’t edit them.

The following example flattens forms using the static Nutrient.processAnnotations operation:

await Nutrient.processAnnotations(
  sourcePath: 'PDFs/form.pdf',
  type: AnnotationType.all,
  mode: AnnotationProcessingMode.flatten,
  destinationPath: 'PDFs/flattened-form.pdf',
);

For more details about using the Nutrient.processAnnotations() operation, refer to the processing annotations guide.
