How Beike Scaled Its Mobile Apps with Flutter: Cross‑Platform Development, Performance, and Developer Efficiency
Beike adopted Flutter to address rapid growth and staffing shortages, achieving over 80% hybrid development, native‑like performance, one‑second hot‑reload cycles, extensive community package usage, and a systematic Flutter infrastructure across dozens of mobile applications.
Beike, a technology‑driven housing service platform serving hundreds of millions of families, faced increasingly complex usage scenarios as its user base expanded, exposing limitations of its original native‑only mobile development approach.
To cope with rapid business growth and a shortage of developers, Beike introduced Flutter, a cross‑platform framework that offers high code reuse and can be integrated into existing native apps, leading to a hybrid development share of more than 80%.
The team confirmed that Flutter can deliver fluid performance comparable to native apps, with core modules such as live‑streaming and animation‑rich pages achieving launch times and smoothness on par with native implementations.
Beyond performance, Flutter dramatically improved developer productivity: the hot‑reload feature reduced UI iteration from minutes to about one second, delivering an estimated hundred‑fold efficiency boost.
Beike also benefited from an active Flutter community; the team leveraged 15 community packages to build a poster‑creation feature and contributed their own pull requests, illustrating the collaborative ecosystem.
Other Beike products, such as the "Beiwo Home Decoration" app, have adopted Flutter for key functionalities like floor‑plan design search and new‑home broadcasting, enabling rapid delivery of a full‑featured 1.0 version within a month.
Today, more than a dozen Beike apps run on Flutter, supported by a comprehensive infrastructure that includes automated environment configuration tools, shared engine containers, UI automated testing, Flutter‑Web fallback solutions, and online exception and performance monitoring systems.
Hundreds of engineers have become Flutter advocates, promoting the technology internally and confidently tackling increasingly complex design and requirement challenges to deliver superior user experiences.
