When building a FlexBuffer using the Builder and adding data that exceeds the default buffer size (2048 bytes), in _newOffset() a larger buffer is created, but never used. This results in a RangeError. Resolve by actually replacing the too small with the new larger buffer. Add a test that verifies this by adding multiple large strings to a vector.

hey @greenrobot-team - for me to merge I need this branch to be up to date with master, but I don't think you have "allow maintainers to make changes" checked. If you wouldn't mind rebasing or updating this, we can try to get it in! note it may take a few attempts if other PRs get merged before I get back to you but after you rebase. |

When building a FlexBuffer using the Dart Builder API and adding data that exceeds the default buffer size (2048 bytes), in the _newOffset() method a larger buffer is created, but never used. This results in a RangeError.
Resolve by actually replacing the too small with the new larger buffer. Add a test that verifies this by adding multiple large strings to a vector.
This was originally reported to us by a user, so additional details can be found in objectbox/objectbox-dart#786 (note that for the reporter the data written that exceeds the buffer size is an integer and in my test a string, so the stack traces and error messages vary slightly).
