Setting Android manifest `<application>` element properties in `pyproject.toml`

Hi,

How to set requestLegacyExternalStorage to true through pyproject.toml file for flet project?

I tried

[tool.flet.android]
requestLegacyExternalStorage = true

but it doesn't work.

Any idea?

Thanks.

The solution is addition of pyproject variable to flet build template, so you can access any section/setting in pyproject.toml, for example:

pyproject.toml:

[tool.flet.android]
requestLegacyExternalStorage = true

In flet build template we can access that variable as:

{{ cookiecutter.pyproject.tool.flet.android.requestLegacyExternalStorage }}

Final solution: additional properties to <application> element of Android manifest can be added as:

[tool.flet.android.manifest_application]
requestLegacyExternalStorage = "true"

Hi,

Thanks for your answer.

I tried the solution but it doesn't work.

This is what I get as AndroidManifest.xml file content.

requestLegacyExternalStorage is not in it.
