We build in Flutter and have more than twenty apps in the repository to measure, so these pages are written from build output, dependency lists and our own store listings rather than from benchmarks somebody else ran. Each one says how it was measured, and says what it could not measure.
What a Flutter app actually weighs
Six Flutter apps from one team on one pinned SDK run from 19.9 MB to 85.2 MB. What sets the floor is what you attach to the framework.
Read the write-up →How much of a forked app is still its parent
We measured 29 Flutter apps against the app each was forked from: 7% to 41% of source files shared, and none of it is the feature.
Read the write-up →Every one of our App Store listings said English only
Our nine live iPhone apps all list one language on the App Store. Seven are translated, Taco Rain into twelve. The cause was a missing folder.
Read the write-up →What is and is not here
Every app we ship is Flutter, so that is what we can write about first-hand. Where a page compares anything else it will say that the numbers are somebody else's, because the only reason to read this section rather than the documentation is that the figures came off our own apps.
None of these pages concludes that a framework or a package is the right one. They describe what a choice cost us, on our apps, on a stated date. If you are here for the consumer side instead, the apps are on our apps page and the writing about other companies' apps is in the reviews.
