There was similar issue fixed and merged very recently, #73726 ,flutter/plugins#3411,
You may try to switch to latest master and check to see if it resolves your issue. Or you may also cherry pick the changes from the merged PR until a new camera version is available.
I am going ahead and closing this as duplicate and already fixed. If you disagree or think this is still occuring with new changes, write in comments and I'll reopen it.
Thanks.
