A new Flutter project.
|

|
||
|
||
A few resources to get you started if this is your first Flutter project:

|
||
samples, guidance on mobile development, and a full API reference.
|
||
|
||
# 开发细节注意
|
||
## 布局
|
||
- scaffold home 主视图拆成函数
|
||
- 颜色放在common里统一管理，使用class静态属性调用
|
||
- 不同结构使用注释标识，使用end结尾结构更清楚
|
||
## 导入资源和图片
|
||
- 固定写法 assets/images/3.0x flutter自动适配几倍图
|
||
- 在pubspec中导入资源，在commont新建assets类管理资源
|
||
- 使用stack进行叠加，使用aligment进行对齐管理
|
||
## 字体和文本设置
|
||
- 导入字体，设置family和路径，以及不同字体对应的字重
|
||
- text，使用style配置样式，fontsize是字体大小，height是行高，是个比值，使用具体的行高值/字体大小
|
||
## 增加倒计时
|
||
- 将无状态组件转成有状态组件，信息变化
|
||
- 使用future.delayed实现倒计时，注意使用async
|
||
- 使用三目运算符控制显示
|
||
- 将相同组件抽出 |
