How do I run release version of flutter apps ? #11

I would like to measure the memory taken for an Flutter app in release mode.
First verified that debug build works fine, then attempted to build release version of the app, but it failed to run. I think the root cause being kernel_blob.bin is deleted in release mode.

flutter build bundle --release

after this I see that flutter_assets/kernel_blob.bin file is deleted.

wayland embedder fails to run if this file is missing.

error reported
ERROR: ../utils.cc:56: Kernel blob does not exist.
   <Invalid Flutter Asset Bundle>   
Flutter Wayland Embedder
========================
Usage: `wayland_embedder_meson <asset_bundle_path> <flutter_flags>`
This utility runs an instance of a Flutter application and renders using
Wayland core protocols.

The Flutter tools can be obtained at https://flutter.io/

asset_bundle_path: The Flutter application code needs to be snapshotted using
                   the Flutter tools and the assets packaged in the appropriate
                   location. This can be done for any Flutter application by
                   running `flutter build bundle` while in the directory of a
                   valid Flutter project. This should package all the code and
                   assets in the "build/flutter_assets" directory. Specify this
                   directory as the first argument to this utility.

    flutter_flags: Typically empty. These extra flags are passed directly to the
                   Flutter engine. To see all supported flags, run
                   `flutter_tester --help` using the test binary included in the
                   Flutter tools.
