Missing extension Byte exception

[Sona-098]

Hi ,

I am using latest flutter engine 2.5.3 with flutter version also 2.5.3

When I try to run the built in app that is counter app in Raspberry 3 model b+, I am getting - Unhandled exception: format exception: Unexpected extension Byte.

I did not change anything in the code which is as it is(Built in counter app). And also I have seen the same error when I tried with Gallery app.

Could you please help me with it.

Below is the log.

detected VideoCore IV as underlying graphics chip, and VC4 as the driver.
Reporting modified GL_EXTENSIONS string that doesn't contain non-working extensions.

Any help would be appreciated.

Hey, sorry just noticed I forgot to reply.
This probably some bug inside the platform channel encoder / decoder in flutter-pi.

I fixed some stuff related to that recently, can you try if it works now?
