after_prepare.js

module.exports = function (context) {
    const fs = require('fs');
    const _ = require('lodash');

    const scheme = 'flowkey';

    <intent-filter>

                <category android:name="android.intent.category.BROWSABLE"></category>
                <data android:scheme="${scheme}"></data>
    </intent-filter>
    `;
    const manifestPath = context.opts.projectRoot + '/platforms/android/AndroidManifest.xml';

    if (!androidManifest.includes(`android:scheme="${scheme}"`)) {
        const manifestLines = androidManifest.split(/\r?\n/);
        const lineNo = _.findIndex(manifestLines, (line) => line.includes('@string/activity_name'));
        manifestLines.splice(lineNo + 1, 0, insertIntent);
