First I run flutter build ios --analyze-size.
Then I try to drag & drop the build/ios-code-size-analysis_01.json file into the already open Dart DevTools "Analyze size" window.
Expected behavior: The file is accepted and analyzed.
Actual behavior: I can´t drop the file.
Possible problem: To open DevTools I run the App on a simulated iPhone as I own no real iPhone. But even through the "Open App size tooling" Button the actual behavior persists. Other possible problem: When opening the build/ios-code-size-analysis_01.json file android studio gives a "The file size (10.65MB) exceeds configured limit (2.56MB). Code insight features are not available" & "This document contains very long lines. Soft wraps were forcibly enabled to improve editor performance".
Any idea what I could do different to analyze the size of the app components?
