How to generate QR Code on PDF file in flutter
I had a problem showing that line "has no Unicode support..." to fix that i created a folder fonts on my project and added some true type fonts to it, then i created a pdf theme for the document like below:
var myTheme = ThemeData.withFont( base: Font.ttf(await rootBundle.load("fonts/OpenSans-Regular.ttf")), bold: Font.ttf(await rootBundle.load("fonts/OpenSans-Bold.ttf")), italic: Font.ttf(await rootBundle.load("fonts/OpenSans-Italic.ttf")), boldItalic: Font.ttf(await rootBundle.load("fonts/OpenSans-BoldItalic.ttf")), );then i used the theme in the page of the document and the error was gone, like below:
Page(theme: myTheme,...)I'm not sure if is the same case, but i think you should try.
