APK Blank Screen from Missing libpythonbundle.so in Custom P4A Distro

[auphof]

With a custom P4A distro, the APK does not function on target device, produces blank screen.
There is no libpythonbundle.so in APK.

With a verbose build flet build apk -v --template-dir $HOME/example_helloflet/flet-build-template i observed build.sh issues with popd and pushd. . BUT the build is successful and will install and run, just producing a blank screen.

I am using a customized App template cloned from the Cookiecutter flet-build-template and custom P4A distro.

Expected Behavior:
Normal flow - The build process completes successfully without errors.
Exception flow - If an error occurs the Build should terminate with relevant errors.

Actual Behavior:
The build.sh script errors when executing popd and pushd, resulting in a libpythonbundle.so not being copied into the APK

Suggested fix
I believe all that is needed is to

1. Updated Tag to capture commit regarding build.sh Get rid of pushd and popd due to issue #67 #69
2. Possibly push new Tag to Flutter (Not familiar with Flutter Package Management)
3. update the dependency in https://github.com/flet-dev/flet-build-template/blob/fed5d5fabcabf7ef1c7341acca406605150e5338/%7B%7Bcookiecutter.out_dir%7D%7D/pubspec.yaml#L14

Additional consideration

1. Consider modification of build.sh that on exceptions to terminate the build with appropriate trace

Workaround
Alter the template pubspec.yaml to work with a local version of serious-python using minimum commit of f93ac86(e44dff1)

1. clone https://github.com/flet-dev/serious-python into a local folder
2. modify the template pubspec.yaml to use the local dependency replace serious_python: ^0.7.0 with

dependencies:
  flutter:
    sdk: flutter

  # serious_python: ^0.7.0
  serious_python:
    path: /modules/serious-python/src/serious_python

Steps to Reproduce:

1. flet create example_helloflet
2. Generate a P4A distro and then export SERIOUS_PYTHON_P4A_DIST=$HOME/.local/share/python-for-android/dists/mydist
3. install the cookie cutter template git clone https://github.com/flet-dev/flet-build-template example_helloflet/flet-build-template
4. Initiate the APK build using the flet-build-template
5. Wait the Running Gradle task 'assembleRelease' and the Copying P4A libraries from /home/xxxx/.local/share/python-for-android/dists/mydist and the execution of the build.sh script. Observe the failure when popd and pushd commands are executed.
