Are you interested in cross-platform development but don't have any idea about all the different architectures you want to support? Then just have a look at Flutter. The Flutter SDK allows developers to create native apps for any platform from the same codebase. But how can one codebase be performant on multiple operating systems? Is the same layout native "enough" on different platforms? Come to this talk and find out! I'll try to keep this lightning talk newbie-friendly and understandable for Germans. No Electron, no React Native, no JavaScript.
