所有 loading 动画组件的用法大同小异，都有 duration（动画时长） 和 curve（动画曲线）参数，以及外观样式的设置，下面是一些 loading 动画组件的用法。
49+
50+
51+
52+
小球类的动画组件中有 **BallStyle** 类型的参数，此参数表示小球样式，用法如下：
53+
54+
```dart
55+
BallCircleOpacityLoading(
56+
ballStyle: BallStyle(
57+
size: 5,
58+
color: Colors.red,
59+
ballType: BallType.solid,
60+
),
61+
)
62+
```
63+
64+
65+
66+
![](img/loading_1.gif)
67+
68+
69+
70+
71+
72+
- size：小球大小
73+
- color：小球颜色
74+
- ballType：小球类型，hollow：空心，solid：实心
75+
- borderWidth：边框宽
76+
- borderColor：边框颜色
77+
78+
79+
80+
设置空心球：
81+
82+
```
83+
BallCircleOpacityLoading(
84+
ballStyle: BallStyle(
85+
size: 5,
86+
ballType: BallType.hollow,
87+
borderWidth: 1,
88+
borderColor: Colors.red
89+
),
90+
)
91+
```
92+
93+
![](img/loading_2.gif)
94+
95+
设置动画时长和动画曲线：
96+
97+
```
98+
Ring2InsideLoading(
99+
color: Colors.blue,
100+
duration: Duration(milliseconds: 1200),
101+
curve: Curves.bounceInOut,
102+
)
103+
```
104+
105+
![](img/loading_3.gif)
106+
107+
非小球类的组件使用：
108+
109+
```dart
110+
PacmanLoading(
111+
mouthColor: Colors.blue,
112+
ballColor: Colors.red,
113+
)
114+
```
115+
116+
![](img/loading_4.gif)
117+
118+
119+
120+
```dart
121+
PouringHourGlassLoading(
122+
color: Colors.blue,
123+
)
124+
```
