I try to use HTTP library, "Using on the Browser" but get Error in browser console (Dartium) even for example.
Error:
package:async/src/byte_collector.dart:1 'package:async/src/byte_collector.dart': error: line 42 pos 16: generic functions not supported
T _collectBytes<T>(
^: package:async/src/byte_collector.dart
Downgrade to "0.11.3+2" from "0.11.3+9" helped but I need 0.11.3+9 because of dependence. How to solve the problem with this error?
I think you are using an older Dartium version and need to update to the most recent version.

cable_ready 4.5.0
rails 6.1.4.1
ruby 3.0.2p107
This is a simple example from the basic tutorial (https://www.youtube.com/watch?v=F5hA79vKE_E) I suspect the error I am getting is because either cable_ready or rails evolved a little and created a tiny incompatibility.
I get this error in the JS console:
It is triggered when in my controller I ask cable ready to:
cable_ready["timeline"].console_log(message: "***** cable ready post created")
Which leads to my timeline_channel to:
received(data) {
console.log("******** Received data:", data.operations)
if (data.cableReady) CableReady.perform(data.operations)
}
My interpretation is perform causes this line in cable_ready.js line 13:
operations.forEach(function (operation) {
if (!!operation.batch) batches[operation.batch] = batches[operation.batch] ? ++batches[operation.batch] : 1;
});
Is finding something in the received data that it doesn't like.
That's where my trail ends. Can someone see what I am doing wrong, or tell me what other code you'd like me to include?
Solution: downgrade the version of the cable_ready javascript library.
I previously (maybe a year ago) did this tutorial using CableReady 4.5, Ruby 2.6.5 and Rails 6.0.4 and it worked like a charm back then as well as today.
But today, I tried this tutorial again on a duplicate project--same versions of CR, Ruby, and Rails and now I get java console errors similar to yours.
TypeError: undefined is not a function (near '...operations.forEach...')
perform -- cable_ready.js:13
received -- progress_bar_channel.js:8
I looked at the output of yarn list and saw that cable_ready was version 5.0.0-pre8 on the bad project and it was 5.0.0-pre1 on the good project. The downgrade could be accomplished with yarn add cable_ready#^5.0.0-pre1 in the bad project folder and now both projects work.
FYI for other newbies like me trying to understand how CableReady works: This tutorial gives another example of CableReady, and was also fixed the same way.
I'm trying to make the PDF file with signature with origami gem, follow this example https://github.com/gdelugre/origami/blob/master/examples/signature/signature.rb
Now i just run this signature.rb and got error
[error] Breaking on: ">>\nendobj\n..." at offset 0x1f6f3
[error] Last exception: [Origami::InvalidObjectError] Failed to parse object (no:43,gen:0) -> [ArgumentError] wrong number of arguments (given 1, expected 0; required keyword: year)
I have no idea to move forward :'<
I also found the sign method of gem at https://github.com/gdelugre/origami/blob/master/lib/origami/signature.rb, and have take a look, I can't find any specific things to do :'<
Might this example is outdate?
The error message is known see https://github.com/gdelugre/origami/issues/80
A fix should be available https://github.com/gdelugre/origami/pull/74/commits
But has not been added so use newer file from the fork https://github.com/pocke/origami/tree/fix-ruby-2.7-kwargs-warnings
Specifically you need this updated file and may need to follow any other suggestions from above.
https://github.com/pocke/origami/raw/fix-ruby-2.7-kwargs-warnings/lib/origami/filters/predictors.rb
However it always worth looking for a fork with many more recent improvements such as

I am trying to understand how to read and write data on text files using path_provider plugin.
I've read an example on how to use it on Flutter from here. Then I saw this line of code which I don't understand:
import "package:flutter/foundation.dart";
I tried to comment it out from the code and ran "flutter run":
//import "package:flutter/foundation.dart";
And to my surprise, it ran perfectly. Although it raised some errors like:
E/DartVM (23127): 'dart:core/runtime/libintegers.dart': error: Unexpected tag 0 (Nothing) in ?, expected expression
E/DartVM (23127): ../../third_party/dart/runtime/vm/compiler/intrinsifier.cc: 153: error: Intrinsifier failed to find method ~ in class _Smi
and
E/DartVM (23237): 'dart:typed_data': error: Unexpected tag 15 (DirectPropertyGet) in ?, expected type
E/DartVM (23237): ../../third_party/dart/runtime/vm/compiler/intrinsifier.cc: 153: error: Intrinsifier failed to find method get:x in class _Float32x4
But it ran well. I don't know why. When should I use it? What method from the code did the foundation.dart was used?
I would appreciate any kind of enlightment. Thanks in advance.
[UPDATE]
I think I understand why foundation library was used in the example code. Maybe because the example code used the "required" constant from the foundation library.
I am trying to use Terminal IDE on Lollipop 5.1.1. Using a Samsung E7 device, a mod version of Terminal IDE is provided by someone on XDA
here:
http://forum.xda-developers.com/showthread.php?t=1340852&page=7
I tried to use javac script in that mod but it gave an unsatisfied link error, saying that:

It is strange that there is a UnsatisfiedLinkError , because it doesn't say that VM cannot find xyz.so library or cannot find xyz method.
I tried using logcat command right after using Terminal IDE's javac script on Device, the odd thing I found from there is :
I/art ( 6558) : rejecting re-init on previously-failed class java.lang.Class<org.apache.harmony.security.fortress.Services>
I couldn't understand why this happened,
The javac script uses android's dalvikvm command to load
com.spartacusrex.spartacuside.external.javac
class. People have faced this rejecting re-init issue on sdk version 20+ but it's not clear to me why this info message uccurs and how to solve it.
I copied /system/lib/libjavacrypto.so to Terminal IDE's ~/system/lib folder and now javac and dx tools are working.
It seems like Google messed up with things in /system/lib which resulted in errors.
Answering so someone else might find it useful.

It works but the error message upset me a lot and I thought that was something wrong with my code.

ui-bootstrap 0.5.0 has a bug,
(it tries to unbind 'focus' event handler, but handler doesn't exist)
https://github.com/angular-ui/bootstrap/blob/gh-pages/ui-bootstrap-tpls-0.5.0.js#L1226
you can apply this changes
https://github.com/angular-ui/bootstrap/commit/bf30898da27272df75f6c7ff26545ed16ebf1978
or build it directly from github
or wait for 0.6.0
