…为什么要用Flutter
Flutter是谷歌的移动UI框架可以快速在iOS和Android上构建高质量的原生用户界面。 Flutter可以与现有的代码一起工作。在全世界Flutter正在被越来越多的开发者和组织使用并且Flutter是完全免费、开源的。
Flutter有哪些与众不同 1. Beautiful - Flutter 允许你控制屏幕上的每一寸像素这让「设计」不用再对「实现」妥协
2. Fast - 一个应用不卡顿的标准是什么你可能会说 16ms 抑或是 60fps这对桌面端应用或者移动端应用来说已足够但当面对广阔的 AR/VR 领域60fps 仍然会成为使人脑产生眩晕的瓶颈而 Flutter 的目标远不止 60fps借助 Dart 支持的 AOT 编译以及 Skia 的绘制Flutter 可以运行的很快
3. Productive - 前端开发可能已经习惯的开发中 hot reload 模式但这一特性在移动开发中还算是个新鲜事。Flutter 提供有状态的 hot reload 开发模式并允许一套 codebase 运行于多端其他的再比如开发采用 JIT 编译与发布的 AOT 编译都使得开发者在开发应用时可以更加高效
4. Open - Dart / Skia / Flutter (Framework)这些都是开源的Flutter 与 Dart 团队也对包括 Web 在内的多种技术持开放态度只要是优秀的他们都愿意借鉴吸收。而在生态建设上Flutter 回应 GitHub Issue 的速度更是让人惊叹因为是真的快closed 状态的 issue 平均解决时间为 0.29天
除了支持APICloud, Unity3d, React Native外为什么要做Flutter下的RTSP/RTMP播放器
首先Flutter则是依靠Flutter Engine虚拟机在iOS和Android上运行开发人员可以通过Flutter框架和API在内部进行交互。Flutter Engine使用C/C编写具有低延迟输入和高帧速率的特点不像Unity3d一样我们是回调YUV/RGB数据在Unity3d里面绘制Flutter直接调用native SDK效率更高。
其次客户和开发者驱动Flutter发展至今目前还没有个像样的RTSP或RTMP播放器一个播放器不是说有个界面有个开始、停止按钮就可以了一个好用的直播播放器对功能和性能属性要求很高特别是稳定性和低延迟这块不谦虚的说可能是首款功能强大、真正好用的Flutter RTSP/RTMP直播播放SDK。
