createLinuxBuildFile function

void createLinuxBuildFile(String dirPath, [ bool? force ])

Creates the native_splash_screen.cmake file in dirPath. If force is true, it will overwrite the file if it exists.

Implementation

void createLinuxBuildFile(String dirPath, [bool? force]) {
  final file = File('$dirPath/native_splash_screen.cmake');

    logger.w(
      'CMake file already exists at ${file.path}\n'
