A simplified mixin for launching Dart isolates in Flutter
Easy Isolate Mixin
The Easy Isolate Mixin is a powerful mixin package designed to streamline the usage of isolates in your Flutter applications. With this Package, you can easily leverage isolates to perform concurrent and computationally intensive tasks without blocking the main thread.
Key Features
- 🔑 Extremely easy to use
- 👨👦👦 Efficient Isolate Management
- 🔥 Enhanced Performance
- 🥶 Prevents your UI from freezing
- 🛠 Scalability enabled by mixins
Installing
To use the Easy Isolate Mixin package in your Flutter project, follow these steps:
- Depend on it
Add the following line to your project’s pubspec.yaml
file under the dependencies
section:
dependencies:
easy_isolate_mixin: ^1.0.0
- Install it
Run the following command in your terminal or command prompt:
$ flutter pub get
- Import it
Add the following import statement to your Dart code:
import 'package:easy_isolate_mixin/easy_isolate_mixin.dart';
Usage
- Import the package:
import 'package:easy_isolate_mixin/easy_isolate_mixin.dart';
- Create a class and mixin the
IsolateHelperMixin
:
class Service with IsolateHelperMixin {
// Your methods and logic here
}
- Use the
loadWithIsolate()
method to perform expensive work:
class Service with IsolateHelperMixin {
Future<void> performExpensiveWork() async {
final result = await loadWithIsolate(() async{
// Perform your expensive work here
// Return the result
});
}
}
In the performExpensiveWork()
method, you can use the loadWithIsolate()
method from the IsolateHelperMixin
to perform your expensive work in a separate isolate. Simply pass a function to loadWithIsolate()
that contains your expensive computation. The result of the computation will be returned as a Future
.
Handling Big Data
Here’s an example of using loadWithIsolate()
to fetch a list of SomeData
objects:
class DataSource with IsolateHelperMixin {
Future<List<SomeData>> fetchAmountOfData() =>
loadWithIsolate(() => _api.getAmountOfData());
}
The _api.getAmountOfData()
function represents your data fetching logic. It will be executed in a separate isolate, allowing your UI to remain responsive while the data is being fetched. The result will be returned as a Future<List<SomeData>>
.
Note: Make sure the function you pass to loadWithIsolate()
returns a value or a Future
that resolves to the desired result type.
That’s it! You can now leverage the power of isolates to perform concurrent and computationally intensive tasks without blocking the main thread.
