matlab.apputil.package(prjfile) creates an
MLAPPINSTALL file based on the information in the specified PRJ file. The PRJ file
must be an app project file created in R2024b or earlier, for example by using
matlab.apputil.create.
In R2024b and earlier, you could package an app as an MLAPPINSTALL file. Starting in R2025a, you can continue to share and run apps packaged as MLAPPINSTALL files and upgrade existing MLAPPINSTALL files. However, when packaging new apps, use the steps described in Package Apps in App Designer.
