I have the same problem.
You can see that it's keep trying to use ndk version 25.1.8937393 and cmake version 3.18.1
even though I update to latest version of ndk and cmake in android studio.

So I tried to check that what is the problem, I found something.

/Users/***/.pub-cache/hosted/pub.dev/whisper_flutter-0.0.4/android/build.gradle

android {
    // Bumping the plugin compileSdkVersion requires all clients of this plugin
    // to bump the version in their app.
    compileSdkVersion 31

    // Bumping the plugin ndkVersion requires all clients of this plugin to bump
    // the version in their app and to download a newer version of the NDK.
    ndkVersion "25.1.8937393"

    // Invoke the shared CMake build with the Android Gradle Plugin.
    externalNativeBuild {
        cmake {
            path "../src/CMakeLists.txt"

            // The default CMake version for the Android Gradle Plugin is 3.10.2.
            // https://developer.android.com/studio/projects/install-ndk#vanilla_cmake
            //
            // The Flutter tooling requires that developers have CMake 3.10 or later
            // installed. You should not increase this version, as doing so will cause
            // the plugin to fail to compile for some customers of the plugin.
            // version "3.10.2"
        }
    }

There is ndkVersion and cmake version (in comment).
First of all, update ndk and cmake to latest version in Android Studio SDK Manager.
And you can try to change the ndk and cmake version (uncomment it).
After then, no more occur version error.

But, still I'm facing the error "Cannot find source file".

Are there any ideas?

Ok, I finally did it.
You have to download this: https://github.com/ggerganov/whisper.cpp/archive/refs/heads/master.zip
and put whisper.cpp in /Users/***/.pub-cache/hosted/pub.dev/whisper_flutter-0.0.4/src

It's just quick fix solution, have to figure out how to fix this completely.

For iOS,

1. make platform :ios, '13.0' in Podfile
2. (optional) you can this if you got same problem - Specs satisfying the flutter_ffmpeg/https (= 0.3.0) dependency were found, but they required a higher minimum deployment target. tanersener/flutter-ffmpeg#225 (comment)
3. do flutter clean, flutter get pub
4. remove '#include "../../src/whisper_flutter.c"' in /Users/***/.pub-cache/hosted/pub.dev/whisper_flutter-0.0.4/ios/Classes/whisper_flutter.cpp
   you can check there is not that exist.
