AirBnBApp - 만들기

1. 기본 세팅하기

• 파일 구조 잡기

• 이미지 경로 잡기

2. 기본 셋팅하기

• 색깔 정의

import 'package:flutter/material.dart';

// 색상을 정의합니다.
const kAccentColor = Color(0xFFFF385C);

• 여백 정의

import 'package:flutter/cupertino.dart';

// 간격
const double gap_xl = 40;
const double gap_l = 30;
const double gap_m = 20;
const double gap_s = 10;
const double gap_xs = 5;

// 헤더 높이
const double header_height = 620;

// MediaQuery 클래스로 화면 사이즈를 받을 수 있다.
double getBodyWidth(BuildContext context) {
  return MediaQuery.of(context).size.width * 0.7;
}

• 스타일 정의

import 'package:flutter/material.dart';

TextStyle h4({Color mColor = Colors.black}) {
  return TextStyle(fontSize: 34, fontWeight: FontWeight.bold, color: mColor);
}

TextStyle h5({Color mColor = Colors.black}) {
  return TextStyle(fontSize: 24, fontWeight: FontWeight.bold, color: mColor);
}

TextStyle subtitle1({Color mColor = Colors.black}) {
  return TextStyle(fontSize: 16, fontWeight: FontWeight.bold, color: mColor);
}

TextStyle subtitle2({Color mColor = Colors.black}) {
  return TextStyle(fontSize: 14, fontWeight: FontWeight.bold, color: mColor);
}

TextStyle overLine({Color mColor = Colors.black}) {
  return TextStyle(fontSize: 10, fontWeight: FontWeight.bold, color: mColor);
}

  return TextStyle(fontSize: 16, color: mColor);
