The hassle of firebase in flutter

I recently did a firebase integration in flutter to enable cloud messaging services in my app.


I guess you all know what it means.


The power of customized, fast notifications in my flutter app.


I thought being firebase and being flutter has its own perks (since both is backed by Google).

But in reality it's not that easy.



I wanted to integrate androidX support inside my android folder for the flutter app to work.



Well the official doc of integrating firebase to flutter is good(https://firebase.google.com/docs/flutter/setup), but it does not provide you with the full details though.


Apart from the steps described in this doc. I followed some more steps to achieve what I was looking for.


In the app level build.gradle file,

under the dependencies section,

i added the following


implementation 'androidx.multidex:multidex:2.0.0'


 then the 2 lines which includes androidTestImplementation under dependencies section is changed to the following.


 androidTestImplementation 'com.androidx.support.test:runner:1.1.0'

androidTestImplementation 'com.androidx.support.test.espresso:espresso-core:3.1.0'


 Note the androix  here.


Once that is finished under the defaultConfig section please include the following;

multiDexEnabled true


 And also change the minSdkVersion from 16 to 21.


Next, go to the gradle.properties file and add the below lines of code


 android.useAndroidX=true

android.enableJetifier=true


Once all these steps are done, I think you will be good to go.


P.S - I am not sure whether this is fixed at a later point of time, but at the timing of this blog, this steps along with the steps mentioned in the above doc is enough for firebase to work smoothly in flutter.

AI. Will it replace us or...?

AI!! The buzzword is too hot in the market nowadays. Do you have a technical product or an idea? If it doesn't have AI in it, then chances are it's not going to be sold like hot cakes. That is how things have changed lately. It is no wonder why me and my colleagues at Gelato want to see what AI can do in a niche department like customer support and service. And that is exactly what we did. For a company like Gelato, which is in the market for production-on-demand, there are a lot of customer questions you need to answer. It can be related to products, queries about shipping and pricing, and so on and so forth. Thus, our customer support team is always happy to help with these recurring questions. Let's take one example. A customer asked us, "Do you ship to Norway?" Now that is an easy question to answer if you have the knowledge written somewhere where you could refer to it and say, "Yes! As a matter of fact, we do." Following the same thread, the next q...

Replication and transactional guarantee in MongoDB

One of the projects I am working on is using MongoDB as the database solution. And the project makes use of the nifty ORM mongoose to do the heavy lifting of data orchestration. It was high time I implemented transactions to the equation but because of a time crunch I was not able to start with one and the situation merely demands it at times. But come with an architectural change and the way the project was heading it was high time I implemented transactions by using MongoDB. According to MongoDB documentation, transactions are used when the situation requires, “atomicity of reads and writes to multiple documents (in single or multiple collections)”. MongoDB supports multi-document transactions. With distributed transactions, transactions can be used across multiple operations, collections, databases, documents, and shards. Now the piece of code to implement the same was pretty straightforward. // For a replica set, include the replica set name and a seedlist of the members in the URI...

My experience with the Golden signals

In June 2022, I embarked on a quest for a new job opportunity. Fortunately, this endeavor began just before the global job market experienced a significant downturn. I must admit, I faced my fair share of rejections during this period, but I also had an epiphany. It became evident that there was so much more to learn and understand in the world of technology. Coming from a small service-based company, I had encountered limitations in terms of how much I could learn on the job. However, during interviews and conversations with senior developers, I gained valuable insights into the architectural and technical decisions made by teams in various companies. One such company that left a lasting impression on me was Delivery Hero. Their technical blog posts provided a wealth of information, especially for someone like me, transitioning from a smaller company where projects had minimal daily active users compared to the scale of Delivery Hero. One particular blog post that caught my attention ...
