Helvitica has no Unicode support is just a suggestion it is not an Error(I used to thought because since the day i started use of pdf package it shows only this message Never show the pdf which i was expecting ) The error was in OpenFile(in my view) as when i used PdfViewer Package it showed me the desired pdf file

I think you used a non unicoded font in a widget and try to generate a pdf includes it. You need to add this family to your project to use in pdf. Add your font family to your pubspec.yaml file. Should find Helvetica family.

  fonts:
- family: Montserrat
  fonts:
    - asset: assets/open-sans.ttf

Get in code and pass it to your pdf.something widget generator.

final font = await rootBundle.load("assets/open-sans.ttf");
final ttf = Font.ttf(font);

pdf.addPage(Page(
    build: (Context context) {
      return Center(
        child: Text('Dart is awesome', style: TextStyle(font: ttf, fontSize: 40)),
      ); // Center
    }));
