console output |
console output for the running app (stdout and stderr) is |
displayed in the console, below the source code area. |
you can also see the output in the logging view. |

breaking on exceptions |
to adjust the stop-on-exceptions behavior, toggle the |
ignore dropdown at the top of the debugger view. |
breaking on unhandled excepts only pauses execution if the |
breakpoint is considered uncaught by the application code. |
breaking on all exceptions causes the debugger to pause |
whether or not the breakpoint was caught by application code. |

using the logging view |
info note |
the logging view works with all flutter and dart applications. |
<topic_end> |
<topic_start> |
what is it? |
the logging view displays events from the dart runtime, |
application frameworks (like flutter), and application-level |
logging events. |

by default, the logging view shows: |

using the app size tool |
<topic_end> |
<topic_start> |
what is it? |
the app size tool allows you to analyze the total size of your app. |
you can view a single snapshot of “size information” |
using the analysis tab, or compare two different |
snapshots of “size information” using the diff tab. |
<topic_end> |
<topic_start> |
what is “size information”? |
“size information” contains size data for dart code, |
native code, and non-code elements of your app, |
like the application package, assets and fonts. a “size |
information” file contains data for the total picture |
of your application size. |
<topic_end> |
<topic_start> |
dart size information |
the dart AOT compiler performs tree-shaking on your code |
when compiling your application (profile or release mode |
only—the AOT compiler is not used for debug builds, |
which are JIT compiled). this means that the compiler |
attempts to optimize your app’s size by removing |
pieces of code that are unused or unreachable. |
after the compiler optimizes your code as much as it can, |
the end result can be summarized as the collection of packages, |
libraries, classes, and functions that exist in the binary output, |
along with their size in bytes. this is the dart portion of |
“size information” we can analyze in the app size tool to further |
optimize dart code and track down size issues. |

how to use it |
if DevTools is already connected to a running application, |
navigate to the “app size” tab. |
if DevTools is not connected to a running application, you can |
