1 | # DayDart
2 |
3 | A new Flutter package project.
4 |
5 | 
6 | 
7 |
8 | ## Getting Started
9 |
10 | This project is a starting point for a Dart
11 | [package](https://flutter.io/developing-packages/),
12 | a library module containing code that can be shared easily across
13 | multiple Flutter or Dart projects.
14 |
15 | For help getting started with Flutter, view our
16 | [online documentation](https://flutter.io/docs), which offers tutorials,
17 | samples, guidance on mobile development, and a full API reference.
18 |
19 | ## API
20 |
21 | `DayDart` 对象是不可变的，所有的调用都将返回一个新的 `DayDart` 对象。

55 | ----
56 |
57 | ### 解析
58 |
59 | 在 `DayDart` 中传入支持的格式。
60 |
61 | #### 当前时间
62 |
63 | 直接运行 `DayDart` 获取当前时间和日期的 `DayDart` 对象。
64 |
65 | ```dart
66 | DayDart()
67 | ```
68 |
69 | #### 原生创建
70 |
71 | 可以像 DateTime 一样的创建 DayDart 对象
72 |
73 | ```dart
74 | DayDart(2019,12,12);
75 | ```
76 |
77 | #### 时间字符串
78 |
79 | 传入的一个标准的ISO 8601时间字符串。
80 |
81 | ```dart
82 | DayDart.fromString('2019-02-21');
83 | ```
84 |
85 | #### DateTime 对象
86 |
87 | 传入的一个 DateTime 对象。
88 |
89 | ```dart
90 | DayDart.fromDateTime(new DateTime.now());
91 | ```
92 |
93 | #### 复制
94 |
95 | `DayDart` 对象是不可变的，因此可以执行 `.clone()` 来获取一个 DayDart 对象的拷贝。
96 |
97 | ```dart
98 | DayDart().clone();
99 | ```
100 |
101 | #### 验证
102 |
103 | - return bool
104 |
105 | 检测当前的 DayDart 对象是否是一个有效的时间。
106 |
107 | ```dart
108 | DayDart().isValid();
109 | ```
110 |
111 | ### 获取
112 |
113 | 获取日期
114 |
115 | #### 年

123 | ```
124 |
125 | #### 月
126 |
127 | - return int
128 |
129 | 获取月份
130 |
131 | ```dart
132 | DayDart().month();
133 | ```
134 |
135 | #### 日
136 |
137 | - return int
138 |
139 | 获取日期。
140 |
141 | ```dart
142 | DayDart().date();
143 | ```
144 |

164 |
165 | #### 分
166 |
167 | - return int
168 |
169 | 获取分钟。

187 | - return int
188 |
189 | 获取毫秒。
190 |
191 | ```dart
192 | DayDart().millisecond();
193 | ```
194 |
195 | ### 操作
196 |
197 | 我们可以对 `DayDart` 对象增加如下的操作：
198 |
199 | ```dart
200 | DayDart().add(2, Units.H).subtract(13, Units.M);
201 | ```
202 |
203 | #### 增加
204 |
205 | 为时间日期进行增加并返回一个新的 `DayDart` 对象。
206 |
207 | ```dart
208 | DayDart().add(2, Units.H);
209 | ```
210 |
211 | #### 减少
212 |
213 | 为时间日期进行减少并返回一个新的 `DayDart` 对象。

28 | #
29 | # For details regarding assets in packages, see

32 | # An image asset can refer to one or more resolution-specific "variants", see

34 |
35 | # To add custom fonts to your package, add a fonts section here,

37 | # "family" key with the font family name, and a "fonts" key with a
38 | # list giving the asset and other descriptors for the font. For
39 | # example:
40 | # fonts:
41 | # - family: Schyler
42 | # fonts:
43 | # - asset: fonts/Schyler-Regular.ttf
44 | # - asset: fonts/Schyler-Italic.ttf

46 | # - family: Trajan Pro
