在终端执行 flutter run --enable-software-rendering即可，运行 flutter help run可以看出该参数的含义是：
Run your Flutter app on an attached device.
Usage: flutter run [arguments]
-h, --help Print this usage information.
--debug Build a debug version of your app (default mode).
--profile Build a version of your app specialized for performance profiling.
--release Build a release version of your app.
--flavor Build a custom app flavor as defined by platform-specific build setup.
Supports the use of product flavors in Android Gradle scripts, and the use
of custom Xcode schemes.
--trace-startup Trace application startup, then exit, saving the trace to a file.
--verbose-system-logs Include verbose logging from the flutter engine.
--route Which route to load when running the app.
-t, --target=
If the --target option is omitted, but a file name is provided on the
command line, then that is used instead.
(defaults to "lib\main.dart")
--observatory-port Listen to the given port for an observatory debugger connection.
Specifying port 0 (the default) will find a random free port.
--[no-]pub Whether to run "flutter pub get" before executing this command.
(defaults to on)
--[no-]track-widget-creation Track widget creation locations. This enables features such as the widget
inspector. This parameter is only functional in debug mode (i.e. when
compiling JIT, not AOT).
--start-paused Start in a paused mode and wait for a debugger to connect.
--enable-software-rendering Enable rendering using the Skia software backend. This is useful when
testing Flutter on emulators. By default, Flutter will attempt to either
use OpenGL or Vulkan and fall back to software when neither is available.
--skia-deterministic-rendering When combined with --enable-software-rendering, provides 100% deterministic
Skia rendering.
--trace-skia Enable tracing of Skia code. This is useful when debugging the GPU thread.
By default, Flutter will not log skia code.
--trace-systrace Enable tracing to the system tracer. This is only useful on platforms where
such a tracer is available (Android and Fuchsia).
--dump-skp-on-shader-compilation Automatically dump the skp that triggers new shader compilations. This is
useful for wrting custom ShaderWarmUp to reduce jank. By default, this is
not enabled to reduce the overhead. This is only available in profile or
debug build.
--[no-]await-first-frame-when-tracing Whether to wait for the first frame when tracing startup
("--trace-startup"), or just dump the trace as soon as the application is
running. The first frame is detected by looking for a Timeline event with
the name "Rasterized first useful frame". By default, the widgets library's
binding takes care of sending this event.
(defaults to on)
--[no-]use-test-fonts Enable (and default to) the "Ahem" font. This is a special font used in
tests to remove any dependencies on the font metrics. It is enabled when
you use "flutter test". Set this flag when running a test using "flutter
run" for debugging purposes. This flag is only available when running in
debug mode.
--[no-]build If necessary, build the app before running.
(defaults to on)
--[no-]hot Run with support for hot reloading. Only available for debug mode. Not
available with "--trace-startup".
(defaults to on)
--pid-file Specify a file to write the process id to. You can send SIGUSR1 to trigger
a hot reload and SIGUSR2 to trigger a hot restart.
Run "flutter help" to see global options.
