Reformat Code with dart not working

[nerygarciamx]

when I click REformat code, it moves everything into one line.
I have been trying to fix it for 3 days now. I tried everything. changing lenght to 120, 123, 80
this other option: add inside analysis_options.yaml file inside the project '
formatter:
trailing_commas: preserve
changes in VScode, and nothing.
when I add the commas, and select "reformat code with dart format" it deletes the commas and leave everyhting in one line.
If I indent the code manually. when I do reformat, it moves everything to one line.
I am using android studio otter 2 feature drop
Dart 3.10.3
