Reducing app size

Many developers are concerned with the size of their compiled app. As the APK,
app bundle, or IPA version of a Flutter app is self-contained and holds all the
code and assets needed to run the app, its size can be a concern. The larger an
app, the more space it requires on a device, the longer it takes to download,
and it may break the limit of useful features like Android instant apps.
