Adds `-u`/`--unit-id-debug-info` arguments to `flutter symbolize` to pass paths to DWARF information for deferred loading units. The argument passed via `-u` should be of the form `N:P`, where `N` is the loading unit ID (an integer) and `P` is the path to the debug information for loading unit `N`. The DWARF information for the root loading unit can either be passed by `-d`/`--debug-info` as before or by `--unit-id-debug-info 1:<path>`. Partial fix for https://github.com/flutter/flutter/issues/137527. Additional work is needed to adjust tools built on top of `flutter symbolize` to store and pass along this additional information appropriately when there are deferred loading units.
This directory contains tests for specific flutter commands.
Tests that are self-contained unit tests should go in hermetic/.
Tests that are more end-to-end, e.g. that involve actually running
subprocesses, should go in permeable/.
The ../../tool/coverage_tool.dart script (which is used to collect
coverage for the tool) runs only the tests in the hermetic directory
when collecting coverage.
