# Setup Application Performance Monitoring

- [Setup App Launch](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/setup-app-launch.md): Measure cold app launch latency in your Flutter app, end the launch trace at your own interactable point, and set a custom Apdex target.
- [Setup Screen Loading](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/setup-screen-loading.md): Track how long your Flutter widgets take to load, from the init() method through the end of build(), and find the screens that are slowest to appear.
- [Setup Screen Rendering](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/setup-ui-hangs.md): Detect slow and frozen frames in your Flutter app, grouped by screen, to find where rendering performance is worst. Requires Luciq SDK 19.0 or later.
- [Setup Network](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/setup-network.md): Monitor network requests from your Flutter app with Luciq APM. Covers getting started, payload size capture, Apdex calculation, and custom URL grouping.
- [Setup Flows](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/setup-app-flows.md): Instrument the key user journeys in your Flutter app with Flows to measure how long they take, where users drop off, and what is causing it.
- [SDK Debugging](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/sdk-debugging.md): This page explains the different tools to debug your APM Flutter integration, bypass the 6-hour batching, and change the SDK log level for your Flutter apps.
- [Disabling/Enabling APM](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/disabling-enabling-apm.md): Turn App Performance Monitoring off or on in your Flutter app with one call after SDK initialization, and what happens to data already on the device.
- [Custom Spans](https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring/custom-spans.md): Add custom spans to your Flutter APM setup so operations Luciq does not capture on its own still show up in the spans timeline and in APM metrics.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.luciq.ai/flutter/setup-luciq-for-flutter/setup-application-performance-monitoring.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
