My experience with apps built with Flutter is bad. Appflowy, for example, has extremely poor performance. Both in terms of loading large files and RAM usage. See my performance comparison of block editors[1].

I've built a block editor using Qt C++ and QML that is vastly more performant[2].

Interesting, how old is that Appflowy build? I know Flutter got quite fast recently due to them changing their renderer from Skia to Impeller.

The latest version of Appflowy (currently v0.3.9.1). Maybe it's Appflowy implementation.

I recall that the app Rows had their desktop version written in Flutter and it was extremely fast, able to render billions of rows as a spreadsheet, so I don't think it's a framework limitation but it is likely that Appflowy is not very well implemented.
