Possible to copy iOS App Store transition using Flutter?

问题 Is it possible to copy the transition effect of iOS App Store using Flutter? I tried using Hero Animation by placing two tags into the root layout of both widgets, but animation looks janky or not what I expected. But good thing about this is I am able to do iOS swipe back as I'm using MaterialPageRoute. Source Hero( tag: 'heroTag_destinationScreen', transitionOnUserGestures: true, flightShuttleBuilder: (BuildContext flightContext, Animation<double> animation, HeroFlightDirection

Flutter 混合开发框架模式探索

由 萝らか妹 提交于 2020-12-03 11:12:20
Flutter 混合开发框架模式探索 由于 Google 官方提供的 Flutter 混合式开发方案过于简单，仅支持打开一个 Flutter View 的能力，而不支持路由间传参、统一的生命周期、路由栈管理等业务开发中必要的能力，因此我们需要借助第三方混合开发框架（如 Flutter Boost、Thrio、QFlutter 等）的整合能力才能将 Flutter 混合开发模式投入与生产环境。本文中，我们来研究一下这类混合开发框架的职能、架构与源码。 1. 核心职能与框架目标 一个合格的混合开发框架至少需要支持到以下能力： 混合路由栈的管理：支持打开任意 Flutter 或 Native 页面。 完善的通知机制：如统一的生命周期，路由相关事件通知机制。 对于以上几点目标，我们以 iOS 为例，来逐步挖掘 Flutter 混合开发模式的最佳实现。 注：因为篇幅问题，本文不探究 Android 的实现，从 iOS 切入只是分析问题的一个角度，因 Android 与 iOS 的实现原理一致，具体实现则大同小异。其次因 Channel 通信层代码实现比较繁杂，此文对于 Channel 通信层的讲解仅停留在使用层面上，具体实现读者可以自行研究。 注：本文的 Flutter Boost 版本为 1.12.13，Thrio 的版本为 0.1.0 2. 从 FlutterViewController
