# 调试 Flutter 应用

> 如何调试你的 Flutter 应用。



<?code-excerpt path-base="testing/debugging"?>

There's a wide variety of tools and features to help debug
Flutter applications. Here are some of the available tools:

有很多工具和特性可以帮助调试 Flutter 应用程序，如下列举了一些：

* [VS Code][] (recommended) and [Android Studio/IntelliJ][],
  (enabled with the Flutter and Dart plugins)
  support a built-in source-level debugger with
  the ability to set breakpoints, step through code,
  and examine values.

  [VS Code][]（推荐）和 [Android Studio/IntelliJ][]
  （借助 Flutter 和 Dart 插件）
  支持内置的源代码调试器，可以设置断点，单步调试，检查数值。

* [DevTools][], a suite of performance and profiling
  tools that run in a browser.

  [开发者工具][DevTools]，是一套运行在浏览器的性能及分析工具。

* [Flutter inspector][], a widget inspector available
  in DevTools, and also directly from Android Studio
  and IntelliJ (enabled with the Flutter plugin).
  The inspector allows you to examine a visual
  representation of the widget tree, inspect
  individual widgets and their property values,
  enable the performance overlay, and more.

  [Flutter inspector][]，可在 DevTools 中使用，也可在 Android Studio
  和 IntelliJ（启用 Flutter 插件后）中直接使用。
  检查器让你查看 widget 树的可视化表示、检查
  各个 widget 及其属性值、启用性能叠加层等。
