For executeMultiple, we should probably remove the parameters argument like you mentioned in the issue.

Unless I'm misreading the sqlite3 package, I should be possible to do something like
executeMultiple(
"INSERT INTO books VALUES (?, ?); INSERT INTO authors (?);",
["Sqlite for Dummies", "simolus3", "simolus3"],
);

I don't think that would work, if you call execute with parameters it will only prepare a single statement.
Now, we could potentially make that work by tracking how many parameters each statement has and then skipping those, but it gets trickier if parameters have explicit indexes (INSERT INTO books VALUES (?, ?2); INSERT INTO authors (?2);) or names (VALUES (:title, :author); INSERT INTO authors (:author)).

fixes #122
This PR adds a new method that allows executing all statements in a given string. More context is in the issue.
Based on feedback, I've updated the PR to just use
executewhich doesn't require any changes to the coresqlite3package. However, I still believe this functionality needs a new API. It is valid to expect aResultSetfrom the vanillaexecute. I don't think there is a way to modify that signature to add settings here. The only way to avoid adding an API hereAlso, using
executemeans that it is valid after all to pass parameters. Usingparams.isEmpty/isNotEmptyis probably not a good way to decide whether the user can expect a result back (it's perfectly valid to expect a result fromINSERT INTO mytable (something) RETURNING id.This is implemented using prepareMultiple from thesqlite3package.For web support, an additional PR (simolus3/sqlite3.dart#337) was required in that repo/package. For now I left a dependency override that should be removed before merging.
