A SemanticsData object with label "My Label" had a null textDirection.

[jtanium]

Steps to reproduce

Create an SvgPicture with a semanticsLabel, but no directionality?

I'm only creating this issue because the stacktrace suggested it, and I couldn't find any existing issues related to this.

Expected results

Expected not to get a stacktrace in the console

Actual results

Got an exception.

Code sample

Code sample

    return SvgPicture.asset(
      assetPath,
      width: width,
      height: height,
      colorFilter: ColorFilter.mode(color ?? Colors.black, BlendMode.srcIn),
      semanticsLabel: 'My Label',
    );

Resolution

return Directionality(
      textDirection: TextDirection.ltr,
      child: SvgPicture.asset(
        assetPath,
        width: width,
        height: height,
        colorFilter: ColorFilter.mode(color ?? Colors.black, BlendMode.srcIn),
        semanticsLabel: 'My Label',
      ),
    );

I tried with complete runnable code including your code snippet which worked properly without throwing the reported error.

code

import 'package:flutter/material.dart';
import 'package:flutter_svg/flutter_svg.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;
  @override
  Widget build(BuildContext context) {
    return SvgPicture.asset(
      "assets/search.svg",
      width: 100,
      height: 100,
      colorFilter: ColorFilter.mode(Colors.yellow ?? Colors.black, BlendMode.srcIn),
      semanticsLabel: 'My Label',
      // clipBehavior: Clip.antiAlias,
    );
  }
}

Please check this code and see if using it you still get same error or not. If not, please provide us complete runnable code including the asset you are using.

@darshankawar I don't think this is a problem worth spending a lot of time on. I was getting the stacktrace in the console, but it didn't really seem to affect my app. The stacktrace message just asked to file an issue, so I thought I would put it out here, along with my fix to help someone in the future; and maybe someone would recognize the problem easily.

[darshankawar]

Thanks for the feedback. I tried again by using attributedLabel and wrapping the code with Semantics but couldn't replicate the reported behavior. Based on the stacktrace though, I'll keep the issue open for team's tracking.

For more context: my SVG also had a bunch of non-standard Inkscape tags. Maybe the error was related to those.
