I have created a test by flutter-elinux create test and build it

flutter-elinux build elinux \
     --target-arch=arm64 \
     --target-compiler-triple=aarch64-linux-gnu \
     --target-sysroot=<Absolute_path_to>/ubuntu18-arm64-sysroot

the app can run on the rk3568 weston , but the font is not showed. I can see the assets has the MaterialIcons-Regular.otf My version is 3.13.1 Any suggestions?

test shouldn't have any font asset after creating this test. Please check your project first. Thanks.

I don't know what you mean. I don't have any other fonts

ls build/elinux/arm64/release/bundle/data/flutter_assets/fonts/
MaterialIcons-Regular.otf

I see.

the app can run on the rk3568 weston , but the font is not showed.

What does it mean? No messages like "You have pushed the button this many times:" ?

Did you copy build/elinux/arm64/release/bundle directory to your target device?

You're right. The Text is not be showed and blank.

mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:', // can not be show blank
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium, 
            ), // can not be show blank
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton( // work well
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), 

I have copied bundle to the target device

@RK356X:/root/bundle# ls data/flutter_assets/fonts/MaterialIcons-Regular.otf 
data/flutter_assets/fonts/MaterialIcons-Regular.otf

I have change the backgroundColor to red and can be changed.

How about run flutter-elinux run -d elinux-wayland --release directory on rk3568 without cross-building? Does it work?

My system is linux not ubuntu or centos. So I can not build on the board. I run it with debug and show that

root@RK356X:/root/bundle# ./elinux -b ./ -d
arm_release_ver of this libmali is 'g2p0-01eac0', rk_so_ver is '3'.flutter: The Dart VM service is listening on http://127.0.0.1:34819/ER0wF2Okqq0=/

[HidenoriMatsubayashi]

Okay, but unfortunately, I have no more ideas at the moment.

I have change the font to DejaVuSansMono.ttf and works well. Maybe other fonts will works well too.
