[Web canvaskit] Does not render Thai Text on Edge browser #101738
Description
My project must take the user to write the sign.
Like this.
If I use flutter build web it can't use .toImage by error like Unsupported operation: toImage is not supported on the Web
For a long time to fix this. I found a solution using flutter build web --web-renderer canvaskit. But when I used this, My language using in TextRich() did not show on the mobile web like this below.
When I try to use the English language, it will work normally on the mobile web like this below.
basic code:
final GlobalKey keyRepaint = GlobalKey();
RepaintBoundary(
key: keyRepaint,
child: Stack(
alignment: Alignment.center,
children: [
RichText(
text: TextSpan(children: [
TextSpan(text: "ลงชื่อ"),
TextSpan(text: "ผู้สมัคร"),
])),
SizedBox(width: 280, height: 70),
],
),
),
flutter doctor:
