Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.01982 |
| Opus 5.5 | $0.00012 | $0.00793 |
| Sonnet 5.5 | $0.00006 | $0.00396 |
| Haiku 4.5 | $0.00003 | $0.00198 |
Grade A, and why
flutter-adding-home-screen-widgets scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Implementing Flutter Home Screen Widgets

- Examples
Architecture & Data Flow
Home Screen Widgets require native UI implementation (SwiftUI for iOS, XML/Kotlin for Android). The Flutter app communicates with these native widgets via shared local storage (UserDefaults on iOS, SharedPreferences on Android) using the home_widget package.
- Data Write: Flutter app writes key-value pairs or renders images to a shared container.
- Trigger: Flutter app signals the native OS to update the widget.
- Data Read: Native widget wakes up, reads the key-value pairs or images from the shared container, and updates its UI.
Flutter Integration Workflow
Use this checklist to implement the Dart side of the Home Screen Widget integration.
- Step 1: Initialize the App Group. Call
HomeWidget.setAppGroupId('<YOUR_APP_GROUP>')ininitState()or app startup. - Step 2: Save Data. Use
HomeWidget.saveWidgetData<T>('key', value)to write data to shared storage. - Step 3: Trigger Update. Call
HomeWidget.updateWidget(iOSName: 'YourIOSWidget', androidName: 'YourAndroidWidget')to notify the OS. - Step 4: Validate. Run Flutter build -> review console for missing plugin registrations -> fix.
iOS Implementation Workflow
If targeting iOS, implement the widget using Xcode and SwiftUI.
- Step 1: Create Target. Open
ios/Runner.xcworkspacein Xcode. Add a new Widget Extension target. Disable "Include Live Activity" and "Include Configuration Intent" unless explicitly required. - Step 2: Configure App Groups. Add the App Groups capability to both the Runner target and the Widget Extension target. Ensure the App Group ID matches the one used in Dart.
- Step 3: Define TimelineEntry. Create a struct conforming to
TimelineEntryto hold the data passed from shared storage. - Step 4: Implement TimelineProvider.
- In
getSnapshotandgetTimeline, instantiateUserDefaults(suiteName: "<YOUR_APP_GROUP>"). - Extract values using
userDefaults?.string(forKey: "your_key"). - Return the populated
TimelineEntry.
- In
- Step 5: Build UI. Implement the SwiftUI
Viewto display the data from theTimelineEntry. - Step 6: Validate. Run Xcode build for the Widget Extension -> review provisioning/App Group errors -> fix.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flutter-adding-home-screen-widgets is a skill published in the GitHub repository build-with-dhiraj/ai-workflow-framework-portability-kit (5 stars, last pushed 21d ago), licensed MIT. It adds 29 tokens to every session and 1,982 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-21.
