week5

Lab 5 – HTTP & async

⚠️ Formatting & analysis

To get full marks for the task, your code must be properly formatted and must not produce any analysis issues. That is, running the following commands in the week's directory must not report any issues or changes:

dart format --output=none --set-exit-if-changed .
flutter analyze

In the task for week 5, you'll be fetching data from a RESTful HTTP service – pokeapi.co. You only need to modify lib/task.dart (and the pubspec, to add dependencies if needed).

⚠️ Isolate support

Part 2 & 3 will not work on the web – run the app on one of the mobile or desktop targets.

Part 1 – loadPokemonSlow

• Use the library of your choice (I recommend Dio)
• Parse the responses to return data of a random Pokémon

Part 2 – loadPokemonFastAndEasy

• You'll find that part 1 causes the app to freeze while the data is being parsed.
• Offload the fetching & parsing to a separate isolate

Part 3 – loadPokemonFastAndComplex

• Now do the same thing as part 2, but manually create and control the isolate.
