If you are a Flutter developer, you might have come across the terms Provider
and Riverpod. These are two of the most popular state management solutions in
the Flutter community. In this blog post, we will discuss the differences
between Provider and Riverpod and help you decide which one you should use.
What is Provider?
Provider is a state management solution for Flutter that allows you to manage
the state of your application simply and efficiently. It works by creating a
"provider" object that holds the state of your application and can be accessed
by any widget in the widget tree. Provider uses the InheritedWidget mechanism
of Flutter to propagate the state changes to the widgets that depend on
it.
What is Riverpod?
Riverpod is a state management solution for Flutter that was developed as a
more modern and efficient replacement for Provider. It uses the Provider API
but offers a simpler and more declarative syntax for creating providers.
Riverpod also offers better performance and more accessible testing
capabilities compared to Provider.
Provider vs Riverpod
Both Provider and Riverpod are excellent state management solutions for Flutter. However, there are some differences between the two that you should consider before choosing one.
| Feature | Provider | Riverpod |
|---|---|---|
| Syntax | Verbose | Declarative |
| Performance | Rebuilds all widgets that depend on a provider | Rebuilds only the widgets that use the updated state |
| Testing | Tricky testing with InheritedWidget | Easier testing with a more modern API |
| Popularity | More established with a larger community | Newer and gaining popularity |
| Compatibility | Compatible with older versions of Flutter | Compatible with Flutter 2.0 and above |
| Ecosystem | Has a larger ecosystem with many plugins and packages | Growing ecosystem with some plugins and packages available |
- Syntax
Provider has a more verbose syntax compared to Riverpod. For example, creating
a provider in Provider involves creating a new class that extends
ChangeNotifier or a similar class. On the other hand, Riverpod allows you to
create providers using a more declarative syntax, similar to how you would
create a widget in Flutter.
- Performance
Riverpod offers better performance compared to Provider. This is because
Riverpod uses a more efficient mechanism for rebuilding widgets when the state
changes. In Provider, all widgets that depend on a provider are rebuilt when
the state changes, even if they don't use the updated state. Riverpod only
rebuilds the widgets that actually use the updated state.
- Testing
Riverpod offers easier testing capabilities compared to Provider. In Provider,
testing can be tricky because of the use of the InheritedWidget mechanism. On
the other hand, Riverpod uses a more modern and easier-to-test API that makes
testing a breeze.
Conclusion
In conclusion, Provider and Riverpod are both solid choices for state
management solutions when it comes to Flutter. Provider is a more
tried-and-true option that has been utilized by a significant number of
Flutter developers over the course of its development. On the other hand,
Riverpod is a more recent and cutting-edge technology that not only provides
improved performance but also makes testing capabilities more simpler.
Riverpod is the tool that we recommend using whenever a new Flutter project is
initiated. If, on the other hand, you are currently using Provider in an
ongoing project, there is no reason to convert to Riverpod unless you are
experiencing problems with the project's performance or testing unless you are
already using Riverpod. Your preference and the specific needs of your project
will ultimately determine whether you go with Provider or Riverpod as your
choice.
