Libraries dan import

import, show/hide, as alias, deferred.

Pahami konsepnya

import "dart:math"; membawa pustaka core. import "package:nama/lib.dart"; untuk paket eksternal. import "file.dart" show fungsiA; menyaring. as memberi alias: import "dart:math" as m;. deferred as lazy memuat saat dibutuhkan.

Coba contoh kode

import "dart:math" as m;

void main() {
  print(m.max(3, 8));
  print(m.min(3, 8));
  print(m.pow(2, 10));
}

as m memberi alias — semua akses lewat m.max, m.min. Tanpa alias, max langsung tersedia.

Latihan singkat

Uji: max(3,8,1,9,4) — harus `9`.
