nonvegetable/shiksha-diary ? reverse-engineered prompt

Build me an Android app for home tuition teachers that works fully offline and keeps all student data on the phone. I want it to feel simple and easy to use, with big readable text and a calm interface.

The app should let me add students, edit them, archive or delete them, and assign subjects to each student. I also want a syllabus setup where I can manage boards, standards, subjects, and chapters, plus a teaching workflow where I can tick off stages like lesson, oral practice, written practice, and revision. The main flow should be quick, open a student, choose a subject, choose a chapter, then mark the stages done for that class.

Please also include a home screen with quick stats and recent students, school and exam tracking, and a settings area for managing the workflow and syllabus. Use local storage so it keeps working without internet, and make sure progress stays saved after closing the app. If you need to check current Flutter docs or best practices, look them up online.
