Flutter will use an SQLite database file to write a description of a sequence of scenes that can be read to play them back for further debugging and profiling (only present in debug & profile modes).

The SQLite sources are derived from the amalgamated sources generated from either the upstream Fossil or Git repositories. Pulling in sources from the repository itself is not recommended both for performance (as outlined in the section on amalgamation) and size reasons (the entire repo is 140 MB at --depth=1)

A one-click mechanism to update and amalgamated sources, version information, and an optimized set of GN rules is present in https://github.com/chinmaygarde/sqlite. The new repo can either be initialized to chinmaygarde/sqlite@ef1f9f4 or left bare and I can fill it with the contents of that repo.

The LICENSE has been verified to be part of the "unencumbered" list here. cc @Hixie in case he wants to verify the repo layout.
