What would a world with room temperature superconductors look like? Besides more powerful and compact computers we’d als

get_it: It says it right on the box. get_it is not a state management solution — but people keep using it like one. It’s very messy if used as a state management solution, and you honestly might be better off just declaring floating variables in files.

No dependency on BuildContext: This is also a great one, for reasons mentioned already. Sometimes, you just can’t get the BuildContext where you need it. This might be the onAppClose listener, that you set up right in the main function.

The ultimate dream is to be able to make this technology at room temperature. One of the highest recorded temperatures for superconductors is 138 Kelvin (-211° F or -135° C). Still nowhere near the average room at 70° F (21° C).

But the devil is in the details. The reason the liquid helium was so important is because it helped cool the superconducting materials to extremely low temperatures. Most superconductors work only at hundreds of degrees below the freezing point of water, near what we call absolute zero.

Absolute zero is the coldest possible temperature. It’s represented as 0 Kelvin (-273.15° Celsius or -459.67° Fahrenheit). The movement of atoms at this temperature is almost nothing. This is the key to superconductors. Normally, electrons moving through a wire will collide with other vibrating atoms, thus causing energy loss and resistance. But because the atoms are almost entirely non-moving at such frigid temperatures, electrons can pass by without collisions and without energy loss. Different materials will need to be lowered to different temperatures — known as their critical temperature — before they become superconducting. Interestingly enough, materials like gold, silver, and copper cannot be made into superconductors even though they are some of the best room-temperature conductors.

Compile Safety: This is, by far, the best innovation to come to state management. If your code compiles, you’re good. No longer are we going to wonder why we can’t find our provider in the tree. This is an innovation that is huge and will save you so, so much time.

There is a reason why power plants are often erected so close to busy cities. Up to 30% of the electricity they generate can be lost in the transmission lines. This is a common problem with electrical appliances. Much of the energy is lost to heat. That is also why much of the space of a computer, for example, is devoted to cooling parts which help combat the heat generated from the circuits. Making advancements in the field of superconductors would enable us to make computers 1,000 times more powerful than the one you have in your home today. These next generation computers would be more compact, and internal superconducting connections would mean much faster processing.

Less boilerplate than Provider: RiverPod does a great job trimming the fat of Provider, allowing you to just register a single top level store and then be done, rather than having to provide each provider individually. (Some of you might be wincing at the thought of everything in one place — Don’t worry! You can scope your pods if necessary.)

redux / fish_redux / mobx: These all came from React, and have very similar styles — but I think that it quickly becomes clear that React and Flutter are two different but similar beasts. These work, and if you’re used to them, then you can use them, but the state management designed for Flutter work the most cleanly, in my opinion.

GetX. I’m not a fan of GetX. GetX tries to get a lot done, which limits your flexibility. If you’re going for a “Full App” package, then GetX is the way to go. I’ve tried it and didn’t like it — but if it’s what works for you, then great!

Simply put, superconductors solve the problem of energy lost to heat. These special materials can carry electricity without losing any of that energy. This is an astounding feature. It sounds as fantastical as that image of a perpetual motion machine ambling along without any energy input. Impossible. And yet consider this: scientists were able to maintain an electrical current inside a superconducting ring for over 2 years. And this without the original energy source. In fact the only reason the current stopped is because the scientists lost access to their liquid helium, not because the current couldn’t have continued running. Our experiments lead us to believe that currents within superconducting materials could last hundreds of thousands of years, if not more. The electrical current in superconductors can flow forever, transmitting energy without any cost to us.

king blind spot to think that software engineering itself isn’t an ecosystem of privilege and power. It’s the folks whose parents could afford for them to have a computer growing up. It’s the folks who could afford to go to school.

With the 80’s came the discovery of a new class of superconductors. These were made, oddly enough, from ceramics, and could be produced at much higher temperatures than former materials. Where other materials had to be just a few degrees above 0 Kelvin, the ceramics became superconducting at 92 Kelvin. They were so easy to make that anyone with $50 and a microwave could recreate them at home. This is strange. Ceramics are usually poor conductors. To this day, physicists aren’t entirely sure why these special ceramics become superconducting at all.

RiverPod is just Provider in a different skin — a sleeker, better skin. If you’re starting a new app and want to go the Provider route, I highly recommend you consider RiverPod.
