Open source Hongmeng cross-platform ecology ushered in a major breakthrough! From Kotlin to Flutter, from React Native to Electron, developers can migrate Android/iOS/Web to full-scenario devices at zero cost. This article will explain the core capabilities and application scenarios of each technology stack to help you quickly select and efficiently land.
With the rapid maturity of the open source OpenHarmony ecosystem, cross-platform development has become a mainstream solution for multi-terminal deployment. The SIG group of open source Hongmeng cross-platform framework has completed the deep adaptation of KMP, Cordova, React Native, Flutter, Ionic, Chromium, Electron, Qt and other mainstream technology stacks, so that Android/iOS/Web/desktop applications can migrate to the full-scenario devices in Hongmeng.
