react-native android dynamic node_modules discovery when hoisted in mono-repo
When using a react-native inside a mono-repo, builds dont work when node_modules are hoisted. To fix this, we make a few changes in gradle files.
"apps/mobile-app/android/app/build.gradle" -> update with below changes
reactNativeDir = new File(["node", "--print", "require.resolve('react-native/package.json')"].execute(null, rootDir).text.trim()).getParentFile().getAbsoluteFile()
codegenDir = new File(["node", "--print", "require.resolve('@react-native/codegen/package.json')"].execute(null, rootDir).text.trim()).getParentFile().getAbsoluteFile()
cliFile = new File(["node", "--print", "require.resolve('react-native/package.json')"].execute(null, rootDir).text.trim(), "../cli.js").getAbsoluteFile()
