How to add Arabic chars in flutter pdf generating

just add textDirection: pw.TextDirection.rtl to the Text widget , like this :

 pw.Page(      build: (pw.Context context) => pw.Center(        child: pw.Text(test, style: pw.TextStyle(fontSize: 80,font: myFont),textDirection:         pw.TextDirection.rtl),      ),    ),

Note: Problems may occur if the text contains some numbers

if all your widget has rtl parent all widget with pw.Directionality and set TextDirection.rtl , or use TextDirection.rtl in single text widget

just add theme: ThemeData.withFont(base: ttf,) to the Page widget, like this:

  var data = await rootBundle.load("fonts/IRANSansWeb(FaNum)_Bold.ttf");  final ttf = Font.ttf(data); Page(      pageFormat: PdfPageFormat.a4,      theme: ThemeData.withFont(        base: ttf,      ),      orientation: PageOrientation.landscape,      build: (Context context) {return Align(  alignment: Alignment.center,  child: new Column(      mainAxisAlignment: MainAxisAlignment.spaceBetween,      crossAxisAlignment: CrossAxisAlignment.center,      children: [        Column(          children: [            Row(              children: [                Text(                  'خلیج فارس',                 textDirection: TextDirection.rtl,                )              ]            )          ]        ),        Column(          children: [            Image(compareChartImage),          ]        ),        Column(          children:[            Image(timingChartImage),          ]        )      ]  )); })
