I'm not gradle professional but in build.gradle, there's an explicit CMake version config. I'm not sure why it is there and what happens if I remove the version specification...

https://github.com/espresso3389/pdfrx/blob/ee3494c26e192bc91773246bc95e7375ad6559b9/android/build.gradle#L45

[espresso3389]

On 0.4.31, I removed the version spec. on build.gradle anyway.

[espresso3389]

flutter/flutter #75600 seems very similar.

[espresso3389]

And, it seems that I can specify CMake version like version "3.18.1+" though it may hit gradle/gradle #16555.

[espresso3389]

New flutter projects such as pdfrx's example already has the following gradle version. Not affected by the gradle issue anyway.

0.4.37 contains the fix explained above:
