# Pub.dev Scraper (`crawlerbros/pub-dev-scraper`) Actor Scrape Pub.dev, the official Dart and Flutter package repository with 40K+ packages. Search packages, fetch package details with scores, get all packages by a publisher, or browse trending packages. - **URL**: https://apify.com/crawlerbros/pub-dev-scraper.md - **Developed by:** [Crawler Bros](https://apify.com/crawlerbros) (community) - **Categories:** Developer tools, Automation, Other - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 4 bookmarks - **User rating**: 5.00 out of 5 stars ## Pricing from $3.00 / 1,000 results This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Pub.dev Scraper Scrape **Pub.dev** — the official Dart and Flutter package repository with 40,000+ packages. Search by keyword, fetch a specific package with full scoring data, get all packages by a publisher, or browse trending Flutter packages. No API key, login, or proxy required. Uses the free public Pub.dev REST API. ### Features - **Search** packages by keyword with full pagination - **Fetch a specific package** by name with scores (pub points, likes, popularity) - **List all packages by a publisher domain** (e.g. flutter.dev, dart.dev) - **Browse trending packages** sorted by popularity score ### Input | Field | Type | Description | |---|---|---| | `mode` | select | `search` / `byPackage` / `byPublisher` / `trending` | | `query` | string | Search keyword (mode=search) | | `packageName` | string | Exact package name (mode=byPackage) | | `publisherId` | string | Publisher domain (mode=byPublisher), e.g. `flutter.dev` | | `maxItems` | integer | Max records to emit (1–1000, default 20) | #### Example inputs **Search packages:** ```json { "mode": "search", "query": "flutter", "maxItems": 20 } ```` **Fetch a specific package:** ```json { "mode": "byPackage", "packageName": "dio" } ``` **Get all packages by a publisher:** ```json { "mode": "byPublisher", "publisherId": "flutter.dev", "maxItems": 50 } ``` **Browse trending packages:** ```json { "mode": "trending", "maxItems": 20 } ``` ### Output Each record contains: | Field | Type | Description | |---|---|---| | `package` | string | Package name | | `version` | string | Latest published version | | `description` | string | Package description | | `homepage` | string | Package homepage URL | | `repository` | string | Source code repository URL | | `publishedAt` | string | ISO timestamp of latest version release | | `likes` | integer | Number of pub.dev likes | | `popularityScore` | number | Popularity score (0.0–1.0) | | `pubPoints` | integer | Pub points awarded | | `maxPoints` | integer | Maximum achievable pub points | | `sdkConstraint` | string | Dart SDK version constraint | | `publisherId` | string | Publisher domain (e.g. flutter.dev) | | `pubDevUrl` | string | Direct pub.dev package page URL | | `scrapedAt` | string | ISO timestamp when record was scraped | #### Example record ```json { "package": "dio", "version": "5.4.0", "description": "A powerful HTTP client for Dart, which supports Interceptors.", "homepage": "https://github.com/cfug/dio", "repository": "https://github.com/cfug/dio", "publishedAt": "2024-01-15T10:00:00.000Z", "likes": 5000, "popularityScore": 0.9932, "pubPoints": 160, "maxPoints": 160, "sdkConstraint": ">=3.0.0 <4.0.0", "publisherId": "dart.cn", "pubDevUrl": "https://pub.dev/packages/dio", "scrapedAt": "2026-05-25T10:00:00+00:00" } ``` ### FAQs **Does this require an API key or login?** No. The Pub.dev public API is freely accessible without authentication. **What is the `trending` mode?** Trending mode queries Pub.dev for Flutter SDK packages sorted by popularity score, giving you the most widely-used packages in the Flutter ecosystem. **How does the search mode work?** Pub.dev returns a page of package names per request. For each name returned, the scraper fetches the full package details, score, and publisher in parallel. This ensures you get complete metadata for every result. **What are pub points?** Pub points (0–160) are awarded by Pub.dev based on documentation quality, code conventions, platform support, and other quality criteria. Higher scores indicate better-maintained packages. **Which fields are always present?** `package`, `pubDevUrl`, and `scrapedAt` are always populated. All other fields are omitted if not available for a package. **Can I filter by SDK (Dart vs Flutter)?** Use the search query with SDK filters: e.g. `sdk:flutter` or `sdk:dart`. Combine with a keyword: `"flutter dio"`. **What is a publisher ID?** Publisher IDs are verified domain names registered on Pub.dev (e.g. `flutter.dev`, `dart.dev`, `google.dev`). They certify that packages are officially maintained by that organization. # Actor input Schema ## `mode` (type: `string`): What to fetch from Pub.dev. ## `query` (type: `string`): Keyword to search for (mode=search). Example: flutter, dio, provider, riverpod. ## `packageName` (type: `string`): Exact package name to fetch details for (mode=byPackage). Example: flutter, dio, provider. ## `publisherId` (type: `string`): Publisher domain to list all packages for (mode=byPublisher). Example: flutter.dev, dart.dev, google.dev. ## `maxItems` (type: `integer`): Hard cap on emitted records (applies to search, byPublisher, and trending modes). ## Actor input object example ```json { "mode": "search", "query": "flutter", "packageName": "provider", "publisherId": "dart.dev", "maxItems": 20 } ``` # Actor output Schema ## `packages` (type: `string`): Dataset containing all scraped Pub.dev package records. # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "mode": "search", "query": "flutter", "packageName": "provider", "publisherId": "dart.dev", "maxItems": 20 }; // Run the Actor and wait for it to finish const run = await client.actor("crawlerbros/pub-dev-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
