Flutter app developers often face the challenge of large APK sizes, which can deter users and harm app store visibility.Reducing the size of Flutter apps is crucial for user engagement and retention, as larger sizes can lead to decreased install conversion rates.One developer managed to shrink a 50MB Flutter app down to 15MB, achieving a remarkable 70% reduction without compromising any features.Optimizing app size not only improves user experience but also enhances app performance and visibility on app stores.
