Summary - Flutter setup

Combine SDK install and doctor output to set up a ready dev environment.

Setup summary

A working Flutter environment comes down to three steps: download the SDK and add its bin directory to PATH, restart the terminal and run flutter doctor to fix missing dependencies. Keep installing tools like Android Studio or Xcode until doctor reports a clean [✓].

# Summary flow
export PATH="$PATH:$HOME/flutter/bin"
flutter --version
flutter doctor

Exercise Check if ready

Write a function hazirMi that takes three bool params (sdk, path, doctor). If all three are true return 'hazir', otherwise 'beklemede'. In main, call hazirMi(true, true, true) and print the result.

Show example solution

void main() {
  print(hazirMi(true, true, true));
}

String hazirMi(bool sdk, bool path, bool doctor) {
  if (sdk && path && doctor) {
    return 'hazir';
  }
  return 'beklemede';
}

Test yourself

flutter doctor reports a [!] warning. What should you do?
- Re-download Flutter
- Delete PATH
- Recompile Dart
- Install the tool in the warning or read the suggestion and fix the issue
Show answer

Install the tool in the warning or read the suggestion and fix the issue — Doctor [!] indicates an issue with a tool; you must install it or follow the suggested fix.
