Mobile App Development with Flutter

Apply for this course

The language and the idea behind the framework.

• Dart essentials hands on
  Types, null safety, async and collections.
• Everything is a widget hands on
  Composition rather than inheritance, and why the tree looks the way it does.
• Stateless and stateful hands on
  Where state lives, and the first mistake everyone makes with it.
• Hot reload and the tooling hands on
  The development loop that makes Flutter fast to work in.

Layouts that survive real devices.

• Layout widgets hands on
  Rows, columns, flex and constraints - and reading the constraint error message.
• Responsive and adaptive design hands on
  One codebase across small Androids, large phones and tablets.
• Material and Cupertino hands on
  Looking native on both platforms without maintaining two designs.
• Urdu and right-to-left support hands on
  Localisation done from the start, because retrofitting it is painful.

The decision that shapes the codebase.

• setState and its limits hands on
  Where it is fine and where it stops scaling.
• Provider and Riverpod hands on
  Sharing state without passing it through ten widgets.
• Choosing an approach
  Why the simplest option that works is usually the right one.
• Separating logic from UI hands on
  So the logic can be tested without a screen.

Apps that talk to something.

• Calling APIs hands on
  HTTP, JSON parsing, and handling the request that fails or times out.
• Local storage and offline hands on
  Caching, and an app that works on a patchy connection - which here is essential, not a nicety.
• Firebase hands on
  Auth, Firestore and push notifications.
• Forms, validation and files hands on
  Including camera and gallery access.

The parts that make it feel like an app.

• Permissions, location and camera hands on
  Asking properly, and handling refusal.
• Navigation and deep links hands on
  Routing, and opening the right screen from a notification.
• Performance hands on
  Jank, rebuild cost and profiling on a real mid-range device.
• Testing hands on
  Widget and integration tests.

Getting it into people's hands.

• Building for Android and iOS hands on
  Signing, icons, splash screens and app size.
• Play Store submission hands on
  Listing, screenshots, policies and the review process.
• Privacy policy and data declarations
  Now mandatory, and a common rejection reason.
• Updates, crash reporting and versioning hands on
  Shipping a fix after launch without breaking existing users.

A published application · 6 weeks

A real app built end to end, working offline, and submitted to the Play Store. Submission counts even if review is still pending.

A final assessment marked out of 100; the pass mark is 50, with 120 minutes to complete it.

• Dart and widget model (20 marks)
• Layout and responsiveness, practical (25 marks)
• State and data handling (30 marks)
• Device features, testing and release (25 marks)

Students who pass the final assessment and have project work verified by their trainer receive a completion letter. It states attendance, the assessment result and the projects verified, and carries a code any employer can check at the verification page.

Pakistan's National Vocational & Technical Training Commission publishes a course-contents document for the trades it funds. This programme is mapped to CIT (Web, Software & Mobile Web Development) — 12 weeks, 5 hours a day, 300 contact hours.

Published by NAVTTC and reproduced here so you can check our syllabus against it. We teach it to those hours: 300 contact hours over 12 weeks, the same as the standard. Read the NAVTTC document.
