When do you choose a ready-made plugin or a custom platform integration?

Short answer

Start with a Flutter API or a trusted plugin, and write a custom integration only when there is a real capability not covered, isolating platform differences behind one contract.

Explanation

A ready-made plugin reduces native code and maintenance, but you must check the supported platforms, the lifecycle, and the quality of maintenance. When a custom need exists, you can build a plugin or channel and link Dart to the host, with a fallback or a clear rejection for the unsupported platform. This is a decision about boundary and cost of ownership, not a rule that one package is always better.

Common mistakes

• Adding native code before checking for a suitable Flutter API or plugin.
• Exposing Android and iOS details in every consumer instead of one adapter.
• Treating an unsupported capability as an ordinary null value with no UX or error policy.

Follow-up questions

• What is the role of platform channels and how do you keep a clear boundary with native code?
