How to use Flutter with Google Sheets, Apps Script, and Codemagic | Codemagic Blog

In this article Jahswill Essien describes how to use Google Sheets with Flutter via Google Apps Script.

This article assumes the following:

  • You have experience using the basics of Flutter and can call APIs and read an existing codebase
  • You have little to no understanding of Google Apps Script
  • You have some experience using Google Sheets or spreadsheets in general

I’m sure many of you reading this post will already be familiar with Google Apps Script and have little/no experience deploying Flutter apps but I also know a lot of Google Apps Script developers are keen to try new stuff.

If deploying mobile apps is a thing that interests you I’d highly recommend also looking at Google no/low code development platform, AppSheet, which enables you to quickly create/deploy apps often using Google Sheets as a backend. If, however, you need custom graphics or pixel perfect UI, solutions like Flutter would be my personal starting point. Enjoy!

Report: Implementing a pseudo 2FA for Web Apps using Google Apps Script

Tags:
| | 0 Comments |

In Google Apps Script, there is the Web Apps. When Web Apps is used, the users can execute Google Apps Script using HTML and Javascript. This can be applied to various applications. When the Web Apps is deployed with “Anyone”, anyone can access the Web Apps. And, there is the case that Web Apps deployed with “Anyone” is required to be used. Under this condition, when 2 Factor Authentication (2FA) can be implemented, it is considered that the security can be higher and it leads to giving various directions for the applications using Web Apps. In this report, I would like to introduce the method for implementing the pseud 2FA for Web Apps deployed with “Anyone” using Google Apps Script.

There can be scenarios where you’d like to publish an Apps Script web app with ‘anyone can access’, but still provide a level of security. Here’s a nice example from Kanshi Tanaike where they use MailApp to email the user a a time limited random passcode.

Magic links and passwordless login are used by a number of services, including Slack, and rather than including a password, as demonstrated in this example, it wouldn’t take much to turn this solution into a passwordless app. There are risks associated with email based authentication and if an attacker already has access to your email so other solutions are worth considering depending on the sensitivity of your web app.

Tech Recruiter Tries Coding pt. 2 — Google Apps (Type)Script

Talking CRMs, Databases, and how to ditch them; this time within the Lead Generation domain. Bonus: pitfalls of a 90s computing mindset! 😅

Previously on Pulse we shared Rafael Romo Mulas’ post, Tech Recruiter Tries Coding. Rafael has recently published part 2 in which they highlight their journey into VS Code, clasp and TypeScript. If you are unfamiliar with TypeScript its a language which transpiles into JavaScript and basically designed to help you write better code. Rafael notes:

… the main difference is you are forced to be more precise, which avoids running into stupid errors! Therefore, to my surprise, it is actually easier to code in TypeScript than JavaScript, even more so for a beginner like me, because:

  • There is not much to “unlearn” from JS, if you just started anyway.
  • You’re alerted when values can be of a type that would cause errors.
  • You’re forced to do something about it, basically debugging in advance.

You can read more about Rafael’s journey in the linked article

Filter a try/catch error message when coding with Google Apps Script

Search a try/catch error message for keywords to determine the error message to log using JavaScript match.

Filter an error message in a try/catch

The following Google Apps Script is designed to exercise how you might go about searching the error message in a ‘try/catch’ for keywords. I wanted this specifically for a tool I built that contains a lot of code (and hence a lot of potential error messages) between a try/catch, for which a very small number of people were experiencing a timezone issue with their Google Sheet file.

The aim was to use a JavaScript ‘match’ to find the keyword timezone and display a set of instructions for the user to resolve the issue themselves instead of just a generic error message.

r/GoogleAppsScript – AutoScript – create Google Apps Script code with help of AI #nocode

I’ve seen a couple of proof of concept solutions for AI generated Google Apps Script code, but this one is the most well developed I’ve seen to date. The AutoScript Add-on isn’t fully verified so if you are trying this out I would recommend using disposable credentials (as a Google Workspace admin I created/used a Cloud Identity account). I’ve only done limited testing but was able to get the add-on to generate a functional Google Apps Script code snippet. Simultaneously both amazing and scary to think a chunk of what I do for a living could be replaced by one of our robot friends.

Have you ever wanted to convert currencies instantly while in Google Chat with colleagues and clients? In this tutorial, we are going to build a Currency Converter Google Chat App with Google Apps Script to do just that.

This tutorial is a multi-media series containing step-by-step video instructions for each stage of the process along with code snippets for each stage, important links and some further details on the more unusual parts of the code.

This is a great video series wrapped in a blog post, which highlights a Google Chat app development process. The particular project presented by Scott Donald is a currency converter but there are many repeatable aspects that would work in a wide range of Google Chat applications. The project is coded in Google Apps Script and the post includes plenty of snippets to help you understand various aspects of Google Chat app development including slash commands and information cards.

Features

  • Maximum runtime – in order to prevent the tool from reaching the limits imposed by Google you can adjust the number of minutes the tool can run for. Change this in the ‘GlobalVariables.gs’ file in the Script Editor.
  • Continue from where it left off – if you have a lot of Google Sheets to convert and the above runtime is reached the tool will save its progress and prompt you to run it again, avoiding any file duplication.
  • HTML popup – as well as the ‘Log’ sheet the tool displays a direct popup to the user if it encounters a problem.
  • PDF counter – after successfully running the tool will include the number of PDFs created as part of the success popup to the user.

Workaround: Checking Existence of File ID in Google Drive without Access token and API key using Google Apps Script

Tags:
| | 0 Comments |

This is a workaround for checking the existence of file ID in Google Drive without both the access token and API key.

When you want to check whether the file of the file ID is existing in Google Drive, generally, you might use Drive API and Drive service (DriveApp) of Google Apps Script. In this case, the scope of Drive API is required to be used. By this, the access token and the API key (in the case of publicly shared files) are required to be used. But, there might be a case that the available scopes are limited. In this post, I would like to introduce a workaround for checking the existence of file ID in Google Drive without both the access token and API key.

This workaround could have been a nice addition to a recent project I was working on to audit a bunch of Google Drive file IDs. As noted in this post a big benefit of the approach is there is no need to include Google Drive authentication scopes to your project. See the source post for the code and explanation.
