I want to search from firebase/firestore, with case insensitive in the sense Foo,foo or FOO can be searched directly without any case restriction. please if some one has any idea how to do.

I'm sorry to say but there is no direct way of case insensitive querying for firestore. But there is a workaround for this problem.

Consider this is your structure of data:

doc 1:
   field: 'Foo'

doc 2:
   field: 'FOO'

doc 3:
   field: 'foo'

You can convert that structure of data to this format:

doc 1:
   field: 'Foo'
   field_insensitive: 'foo'

doc 2:
   field: 'FOO'
   field_insensitive: 'foo'
doc 3:
   field: 'foo'
   field_insensitive: 'foo'

Using this format of data storing you can query for the firestore using the field field_insensitive.
