Testing, performance and security

Ship reliable, fast and secure apps.

📖 Key ideas

  1. Unit, widget/component and integration tests.
  2. Profile performance: frame rates, startup time, memory.
  3. Optimise images and lists; avoid unnecessary rebuilds.
  4. Secure: HTTPS, secure storage, obfuscation, no secrets in code.
  5. Beta test with internal/closed testing and TestFlight.
💡 Real-life example: Testing an app is a test drive on rough roads before selling the car.
