I'm not exactly sure where change() is defined but it is packaged with Laravel and requires doctrine/dbal to also be installed (see the docs).

what you do to make point column not null so i can use index on it?

In your migrations, when defining your point column, just don't set it as nullable (the usual way).
When using change() in the documentation, it's to ALTER a table column that was previously set with DEFAULT NULL; you typically don't need to do this if you CREATE a table.

is there is a way to set default value for point ? point(0,0) is ok for me

Unfortunately this is a MySQL limitation, similarly to BLOB/TEXT/JSON types, you can't set a default value to any GEOMETRY type, otherwise you get:
SQLSTATE[42000]: Syntax error or access violation: 1101 BLOB, TEXT, GEOMETRY or JSON column.
Alternatively you can create a MySQL trigger that updates the value of your POINT column when inserting a NULL value in; something like:

delimiter //
create trigger my_point_trigger before insert on my_point_table
for each row
begin
   if (NEW.point_column is null ) then
      set NEW.point_column = ST_GeomFromText('POINT(0 0)');
   end if;
end
//
delimiter ;

(Untested)
