Can't input char `b` when typing in dart-mode with lsp-dart.

[zw963]

I just report this issue here.

When i typing b, i can saw tips in minbuffer like this, it seem like treat b as a key combination's prefix key.

all others a-z char can typing normally.

following is my minor-mode-list, i guess some minor mode was triggered unexpectedly when typing, anyway, this is my first time occur this can't input b case, thank you.

Sorry, have no idea, are you typing in a treemacs buffer or a normal dart one ? if so, I suggest you ask on treemacs
