React Native seemed like a comparable and equally valid choice to Flutter. Performance, ease of development, and support are roughly equal between the two products. Dart, to me, felt easier to work with than Javascript or Typescript. Flutter SDK tools and VSCode extensions made …

Flutter by Google is well suited where you have to make an app across multiple platforms like iOS, Android, Web, Desktop and you don't have the bandwidth to create multiple teams for the Native app. This makes sure you have a faster development and you don't have to worry about how your product will look across different platforms. It is also very smooth/fast in response, making it close to feel like a Native app, this makes it an easy pick for a Fintech product where speed matters. Flutter by Google also has a huge library of Components, which are well tested and developed by Google's Flutter by Google team itself, making the development even more fast since the majority of required components are already available.

I found Twilio to be excellent and very easy to use for a programmer in all aspects related to voice, SMS, and other features utilizing their API. I found the node client to be excellent and helpful. We previously used the Apex client for Salesforce before it was discontinued. Although we try not to use Twilio from Apex anymore, using that client was easier than implementing our own.

Pros
Google
  • User interface design works great across all platforms, including native styling for iOS/macOS.
  • Native compilation for mobile platforms and a decent rendering engine results in slick apps that can make the most of your device.
  • Dart is a well thought out language and easy to pick up.
  • Makes cross-platform development of good looking GUI apps a doddle.

  • Easy to see my team in one place, when they log in and out and what call status they are in.
  • Twilio is a simple, user friendly way to log in and out of work activities.
  • Excellent services and support.
  • The omnichannel feature which allows agents to get request from all channels.

Cons
Google
  • Occasionally updates to the Flutter SDK result in wide-sweeping changes that seem to not be thoroughly tested and considered. Flutter sometimes evolves too fast for its own good.
  • While the 3rd-party Flutter package ecosystem is vast and rich, 1st-party support for basic things (audio/video playback, battery information, Bluetooth services, etc.) are lacking. You are occasionally forced to rely on an open-source package for use-cases that other platforms have native support for.
  • Documentation, particularly around testing, is lacking. While there are some great docs, like the Dart Style Guide, many Flutter-focused support documents are lacking in quality and real-world usability.
  • Flutter allows you to architect an app however you want. While this is a great feature, it also adds complexity and leads to the current state of Flutter's state management, where there are 50+ options on how to organize your app, with very little official guidance or recommendations from the Flutter team. For a beginner, this can create decision paralysis.

  • Segment’s email identifier is case-sensitive, which is ridiculous because emails themselves are not case-sensitive. This means that if I send a capitalized email address in an identify call, it will create a duplicate user rather than matching it with the lowercase email. I think this is a technical oversight that should be corrected.
  • I’d like to see more information about the eventual transition of existing Frontline customers to Twilio Flex
  • I’d like to see some integrations between Twilio Studio and OpenAI or another open source LLM to provide automated responses, if this hasn’t been done already
  • I would like to be able to drag and move the actual lines connecting the steps in Twilio Studio, sometimes mine can get pretty messy
  • I think a Bug Report form would be beneficial for developers

Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

Usability
Google
Flutter by Google is very easy to start with. The initial setup they provide is very helpful and easy to understand. The default project setup is also good and can be deployed to production without changing much. Flutter by Google provides a huge library of components, which are created and tested by their own team, making the development of application much faster and robust. Flutter by Google also has a huge community support where we can find components built by the community and we can contribute our own components as well, which helps in faster dev time. Applications developed using Flutter by Google are very smooth, almost feels like native, which helps in creating good impression on customers/clients.

Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

Twilio executes what it is designed to do: send SMS messages at scale while providing very good deliverability. I believe that Twilio is very good at what we use for adding SMS messages to our comms strategy. We can see those messages get opened and replied to, which is exactly what we are looking to achieve.

I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries. With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.

I have experience with react and React Native. I would say that the idea behind all those frameworks are quite similar. However, I found the javascript-based frameworks a bit more accessible as you could utilise your javascript knowledge. Here, Flutter works with its own language. This has advantages and disadvantages sometimes. I found the community around javascript frameworks bigger and therefore sometimes more helpful. However, Flutter does a good job here as well. I think the main argument for Flutter is its usability for less experienced developers. If you do not have knowledge in javascript or other programming languages then I think it is much easier to start with Flutter than with another framework like react. I think the package that you get form scratch is better than in the other frameworks were you have to set up and learn a lot more before you can start.

We evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.

Return on Investment
Google
  • The rapid development capabilities of Flutter allow us to build apps we could not have previously considered commercially viable, opening new revenue streams.
  • Free and open licensing made adoption very easy (ie. free/low cost!).
  • In comparison to Qt, our time spent arguing with build tools and perfecting development environments has decreased substantially.
