For mobile development, cross-platform is an unavoidable topic.
In terms of cross-platform mobile technology selection, the two most popular are React Native and Flutter.
Both approaches have their own advantages and disadvantages. Whether it is React Native or Flutter for cross-platform mobile development is a difficult choice for the public.
Of course, my article is not to compare these two technologies, but to introduce another mobile cross-platform technology choice – KMM
What is KMM
The full name of KMM is: Kotlin Multiplatform Mobile, which is a product of jetbrains. It is a business cross-platform mobile development framework.
On KMM's official website, its most concise introduction to itself is:
Share the logic of your iOS and Android apps while keeping the UX native
To understand in Chinese is:
Different platforms share business logic while maintaining their native UI implementations
Advantages of KMMs
Compared with other cross-platform solutions, such as RN and Flutter, KMM has the following advantages:
1. There is no need to build multiple sets of engines (runtimes), and the package volume increment is smaller.
2. For Android developers, there is no need to learn a set of programming languages and programming ideas, and the threshold is lower.
3. Based on the output of double-ended standard components, the risk of audit rejection is small (iOS).
4. Stronger interoperability, supports two-way interoperability with local programming languages, can directly use existing libraries, and avoids repeated construction of many basic components.
5. On the basis of maintaining native development, business modules can be reused.
How to learn KMM
Although the KMM framework has a very low threshold for Android developers, it can't stand the scattered, fragmented and incomplete blog articles on the Internet.
Therefore, the editor here spent a lot of time collecting and sorting out the knowledge points of the KMM framework into " KMM Cross-platform Framework Introduction Tutorial ", and shared this article with friends who are interested in the KMM framework for free.
