【Compose Multiplatform】Implementing Local Persistent Storage with DataStore
1 min read
CrossPlatform#CMP#DataStore#Kotlin
Introduction
In pure Android projects
we can directly use the native DataStore
but in Compose Multiplatform projects
how can we continue using DataStore seamlessly?
This article will introduce how to implement
DataStore local storage in a cross-platform environment
{% include table/compose-multiplatform-category.html %}
Implementation Steps
1. Import Libraries
Add to your .toml file:
Add to your build.gradle.kts:
2. Implement DataStore for Each Platform
Create expect functions and local storage names:
Android platform implementation:
iOS platform implementation:
3. Using DataStore in commonMain
Use the interfaces implemented above
to use DataStore in commonMain:
4. Add Koin Module (Optional)
If you want to use Koin for dependency injection, you can set it up like this:
Conclusion
- Compose Multiplatform allows us to use DataStore in cross-platform projects
- Through proper encapsulation, we can use DataStore API uniformly across different platforms
- Using DataStore simplifies the implementation of local data persistence
- Combined with dependency injection frameworks like Koin, DataStore instances can be better managed
