A powerful, high-performance React Native Camera library.

import fs from 'fs';
import path from 'path';
export function writeToPodfile(projectRoot, key, value) {
  const podfilePath = path.join(projectRoot, 'ios', 'Podfile');
  // get Podfile content as individual lines
  let lines = fs.readFileSync(podfilePath, 'utf8').split('\n');
  // filter out any lines where the given key is already set
  lines = lines.filter(l => !l.includes(key));
  // set the key as the first item in the array so its at the top of the file
  lines.unshift(`${key}=${value}`);

  // write the file back
  const fileContent = lines.join('\n');
  fs.writeFileSync(podfilePath, fileContent, 'utf8');
}
