Flutter - packages install example

-

以charcaters為例，下載檔案後, 將檔案裡面的pubspec.yaml 移到自己的專案，開啟後，更改專案名(我的是dart)，於下方貼上:

dependencies: characters: ^1.0.0 //注意階級，為dependencies的下一層

儲存，VS code會自動執行pub get，如果沒自動就可自行在TERMINAL pub get , 如果是flutter 就 flutter pub get.

如此一來
import 'package:characters/characters.dart';
就可以使用了。

Dart syntax - initSate,Build,deactive, Dispose
