deferred type 'rpi.RpiHardware' is not yet loaded

[tomaszkubacki]

I've made my project and tried to run read example and got:

root@raspberrypi:/home/tomek/projects/switchBoard# /opt/dart-sdk/bin/dart main.dart 
Unhandled exception:
'file:///home/tomek/projects/switchBoard/main.dart': malformed type: line 10 pos 25: deferred type 'rpi.RpiHardware' is not yet loaded
    Gpio.hardware = new rpi.RpiHardware();
                        ^
type error.
#0      _TypeError._throwNew (dart:core-patch/errors_patch.dart:58)

#3      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:148)

my project structure seems to be correct and librpi_gpio_ext.so has been built

When I refactored the examples, I forgot to add a wait for the rpi.loadLibrary(). I have published a new rpi_gpio package (version 0.2.1) that has several fixes including a fixed read example (also see read example code changes).

Please let me know if the revised read example works for you.
