`bool` are [not supported in SQLite](https://github.com/tekartik/sqflite/blob/master/sqflite/doc/supported_types.md#supported-sqlite-types).
What is likely happening is that the `isDone` column value `true` is converted to the string `"true"` so it is crashing in your `TodoItem.map` constructor.
Try to convert (and parse) the value for example to 1 or 0 (int) before insertion or in query args.
