Remove Spaces from Any String using [Custom Code]

Replace the Spaces without custom Letters eg. Underscore, or hyphens.

Step 1: Create a Custom Function: replaceTheSpace

Step 2: Define the Arguments:

  1. (String) replaceWith

  2. (String) stringToReplace

Step 3: Copy And Paste the below code to Code Editor:

import 'dart:convert';
import 'dart:math' as math;

import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';
import 'package:intl/intl.dart';
import 'package:timeago/timeago.dart' as timeago;
import '/flutter_flow/lat_lng.dart';
import '/flutter_flow/place.dart';
import '/flutter_flow/uploaded_file.dart';
import '/flutter_flow/custom_functions.dart';
import '/backend/backend.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import '/backend/schema/structs/index.dart';
import '/auth/firebase_auth/auth_util.dart';

String replaceTheSpace(
  String replaceWith,
  String stringToReplace,
) {
  if (stringToReplace == null) {
    return '';
  }
  return stringToReplace.replaceAll(' ', replaceWith);

Step 4: Define the Text to be Place after Removing Space

Step 5: Define the String from "Spaces" to be removed.

For Example, I'm using them in a Custom Action to Rename the Video Title and Replace the Spaces with underscore:

That's All!

Explanation Regarding Arguments

  1. replaceWith:

    • Purpose: This argument is used to specify the character or string that will replace spaces in the text.

    • Example: If you set replaceWith to a comma (,), it means that any spaces in the text will be replaced with commas.

  2. stringToReplace:

    • Purpose: This argument is used to pass the text where spaces are to be removed or replaced.

    • Example: If you have a sentence like "Hello World" and you set stringToReplace to this sentence, the function/method will operate on this text, replacing spaces according to the rules specified by the replaceWith argument.

In summary, the function/method you are describing takes a piece of text (stringToReplace) and replaces spaces in that text with a specified character or string (replaceWith). This can be useful for tasks such as formatting text, cleaning up data, or modifying strings based on certain criteria.
