New tweet from FlutterDev:

The Spacer widget controls how much space appears between widgets in a row or column. Just add it between two widgets, set the flex factor, and voila. You’ve got customized spacing!

Any idea about encoding CGImage to WebP by libwebp?
Hi there, I published a video to thumbnail plugin : http://bit.ly/2Qua0S0 . But when I was testing it on iPhone and iPhone simulator, I found the color wasn't looking right. I have to use WebPEncodeBGRA instead of WebPEncodeRGBA as CGImage states the data should be "rByte

Run integration test directly on device
Hi,I'm currently evaluating Flutter and am very excited overall, I can image this being the future of app development for most apps.However, I feel like there is something missing in the testing suites:Support for integration tests running directly on the device. Something like instrumentation tests on android.I know that I can run driver tests, however the interaction with the driver is pretty limited, this is only for UI testing.I want to run tests that, for example, connect to the database and run a query.I can write something like this:

void main() async { final DatabaseOpenHelper dbHelper = DatabaseOpenHelper(rootBundle); Database db; setUp(() async { db = await dbHelper.openDb(); }); tearDown(() async { db.close(); }); test("Open db is ok", () async { expect(db.isOpen, true); }); } 

And run it with flutter run integration_test/db_test.dart, and this successfully executes the test. But the tests keeps running afterwards. I could call exit() in tearDownAll(), but this would exit with a non-zero exit code. I would like to have a 0 exit code if all tests succeeded, and a non-zero exit code otherwise.With flutter drive I would get this behaviour but of course I can't run any platform specific code in the target file. I wrote a proof of concept hack to get this behaviour via communication over a flutter driver extension, but I wonder if I keep missing something obvious to get the behaviour I want, I think that's quite a common use case.Here's what I did:db_test.dart (code executed on the host):``` import 'package:flutter_driver/flutter_driver.dart'; import 'package:test/test.dart';void main() async { FlutterDriver driver;setUpAll(() async { driver = await FlutterDriver.connect(); });test("wait for device tests", () async { String result; do { result = await driver.requestData(""); print("test status? $result"); await Future.delayed(Duration(seconds: 1)); } while (result == "waiting"); expect(result, "ok"); });tearDownAll(() async { if (driver != null) { await driver.close(); } }); } ```Basically the code on the host just waits for the driver to finish all tests and then gets the exceptions (if any) or the string "ok" if everything went fine.db_native_test.dart (code executed on the phone):``` import 'package:flutter_test/flutter_test.dart' as test; import 'package:sqflite/sqflite.dart';List<dynamic> exceptions = [];///custom expect method to intercept fails expect(dynamic actual, dynamic matcher, {String reason, dynamic skip}) { try { test.expect(actual, matcher, reason: reason, skip: skip); } catch (err) { exceptions.add(err); rethrow; } }void main() async { final DatabaseOpenHelper dbHelper = DatabaseOpenHelper(rootBundle); Database db;var status = "waiting";enableFlutterDriverExtension(handler: (request) => Future.value(status));test.tearDownAll(() { if (exceptions.isEmpty) { status = "ok"; } else { status = "fail: " + exceptions.join("\n"); } });test.setUp(() async { db = await dbHelper.openDb(); });test.tearDown(() async { db.close(); });test.test("Open db is ok", () async { expect(db.isOpen, true); }); ```This works, can also be used with hot reloading (running it with flutter run), but it's a lot of code, and it's hacky. Is there an easier way?

Flutter + vscode Github versioning integration
For some reason I was always afraid to use version control system because it seems very complicated to me with commits pulls pushes merges.I have an overall idea of what they are but I am too afraid to use them with my app code. I fear i would do something wrong and The code would be in an unrecoverable state after a mistake.Do any of you have any resources for setting up and using github inside vscode for flutter development? Preferably a tutorial video or an article. I am tired of zipping my code folder and backing it up.
