BigMainButton class

页面中的主按钮,支持动态设置背景颜色,置灰

SmallMainButton相比,该按钮是占据父节点分配的最大可用空间,按钮文案居中对齐

按钮是圆角矩形的形状,不支持改变形状。

按钮也存在可用和不可用两种状态,isEnable如果设置为false,那么按钮呈现灰色态,点击事件不响应

大的 提交 按钮 BigMainButtonWidget( title: '提交', )

BigMainButtonWidget( title: '提交', isEnable: false, onTap: () { Toast.show('点击了主按钮', context); }, ), 其他按钮如下:
