Flutter app inquiries

I am in the early process of building my first mobile app using Dart/Flutter and I have 2 questions.

For a Flutter quotes app with static data of more than 1000 quotes that have categories, authors, and content. Also the quotes, the categories, the authors are both in English and my native language.

There will be no user-generated content except favorite quotes for the time being.

1- Do I save my static data in a Dart file or SQflite file?
2- Besides, if I want to add user-generated favorite quotes, how do I do that?
