azlistview

AzListView，Flutter 城市列表，联系人列表，自定义Header，索引，悬停效果。

• IndexBar（A-Z 索引Bar）
• SuspensionView（悬停效果view）
• AzListView（对SuspensionView & IndexBar封装，方便使用）
• SuspensionUtil
• • sortListBySuspensionTag(list) 根据[A-Z]排序。
• • getTagIndexList(list) 获取索引列表。
• • setShowSuspensionStatus(list) 设置显示悬停Header状态。

注意

新AzListView data需要a-z排过序的列表，请自行调用SuspensionUtil.sortListBySuspensionTag(list)。
