fix: skip postcodegen when kotlin is enabled

[patrickkabwe]

Summary

• skip adding the example postcodegen script when Kotlin support is selected so the Kotlin post-script can run instead
• bump the example template to react-native 0.81.4 to align with the latest published version

Testing

• not run

Summary by CodeRabbit

• Chores

  • Updated the React Native dev dependency in the template to 0.81.4, bringing in the latest stability and compatibility improvements.

• Build

  • Optimized code generation handling: Kotlin-based projects now automatically skip an unnecessary post-codegen step, while non-Kotlin projects retain existing behavior. This reduces redundant work and can speed up builds with no change to project setup for other configurations.

Walkthrough

Updates the template’s devDependency react-native from 0.81.1 to 0.81.4. Adjusts NitroModuleFactory.updatePackageJsonConfig so the workspace package.json only includes a postcodegen script when Kotlin is not configured; if Kotlin is present, postcodegen is omitted.

Changes

Cohort / File(s)	Summary
Template dependency bump assets/template/package.json	Bumped devDependency react-native from "0.81.1" to "0.81.4". No other edits.
Nitro package generation logic src/generate-nitro-package.ts	In updatePackageJsonConfig, postcodegen script is now conditional: set to getPostCodegenScript() when Kotlin is not configured; otherwise omitted. No signature changes.

Poem

I thump my paws, a tiny cheer,
A version hop—0.81 draws near.
Scripts now tiptoe when Kotlin’s seen,
Post-codegen hides, the build stays clean.
In burrows of JSON I swiftly weave—
Carrots, commits, and calm release eve. 🥕✨

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The title accurately and concisely describes the primary change: making the postcodegen script conditional when Kotlin support is enabled, which matches the modifications in src/generate-nitro-package.ts and the PR objectives. It is specific, focused, and avoids noisy or vague phrasing; the react-native template bump is a secondary change that does not need to be included in the title.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

src/generate-nitro-package.ts (2)

184-186: Conditionally omit the key instead of assigning undefined.

JSON.stringify will drop undefined, but you can avoid creating the key at all with a conditional spread.

Apply:

-            postcodegen: !this.config.langs.includes(SupportedLang.KOTLIN)
-                ? this.getPostCodegenScript()
-                : undefined,
+            ...(this.config.langs.includes(SupportedLang.KOTLIN)
+                ? {}
+                : { postcodegen: this.getPostCodegenScript() }),

184-186: postcodegen: no external callers; extract duplicated codegen logic

• postcodegen is only referenced in src/generate-nitro-package.ts (script property) and CHANGELOG.md — no other usages (docs/workflows/CI) found.
• Kotlin gate duplicated at src/generate-nitro-package.ts lines 183 and 502; extract a single getCodegenCommand() helper and use it in both places.
