// Use stream: for big file
const fs = require('fs');
const readStream = fs.createReadStream('./doc/custom_button.dart', {encoding: 'utf-8'}); // Create: createReadStream()
const writeStream = fs.createWriteStream('./doc/get_code.dart') // Create createWriteStream()
// Method 1
// readStream.on('data', (chunkData) => {
// console.log('----- NEW CHUNK -----');
// console.log(chunkData);
// // add code to new file
// writeStream.write(chunkData); // Write code
// });
// Method 2: Use Pipe for jon method : read and write
readStream.pipe(writeStream);
