You can refer to the following documentation link for creating form fields with different custom styles. Based on that, we can highlight the form fields with various custom appearances.

Hello,

In this solution, a new textbox field is created from scratch, I want to have an example where I modify the highlight color of a current field inside the pdf form.

Thank you

Kindly refer the following code snippet to modify color properties from existing text box field.

 //Loads an existing PDF document.

 final PdfDocument document =

      PdfDocument(inputBytes: File('input.pdf').readAsBytesSync());

 //Get the loaded form field by index.

 final PdfField field = document.form.fields[0];

 if (field is PdfTextBoxField) {

   //Modify the back color.

   field.backColor = PdfColor(255, 0, 0);

   //Modify the border color.

   field.borderColor = PdfColor(0, 255, 0);

   //Modify the text color.

   field.foreColor = PdfColor(0, 0, 255);

 }

 //Disable default appearance.

 document.form.setDefaultAppearance(false);

 //Save the PDF document.

 File('output.pdf').writeAsBytesSync(await document.save());

 //Dispose the document.

 document.dispose();
