DevTools showing "no tabs available for this application" message

I develop flutter on the TV OS based on linux (not android).I don't use any IDEs, just use command.
my devtools can connect the TV OS by the tcp port forwarding (eg: ssh -R 46003:127.0.0.1:46003 myaccount@my PC IP)
and can show other tabs and work normally,but no debugger tab.I try many versions of devtools,but no one has the debugger tab.

Here is the version about flutter:
Flutter 2.0.3 • channel unknown • unknown source
Framework • revision 4d7946a68d (6 months ago) • 2021-03-18 17:24:33 -0700
Engine • revision 3459eb2436
Tools • Dart 2.12.2

What causes this problem？Thanks!

Start by reproducing the missing debugger tab in DevTools using Flutter 2.0.3 on the Linux-based TV OS with the documented SSH reverse TCP forwarding. Compare the debugger connection with the other tabs that work, and review the DevTools debugger-tab entry point. Done means identifying the cause and restoring or documenting debugger availability for this setup.
