For more info read Google Blog
In your case, I can suggest 3 Possible Solutions.
- Try to Sign in with Email/Password instead of Google Sign In.
- Use url_launcher to redirect the user to the browser.
- If you don't want the user to leave your app
then you can use flutter_custom_tabs
this plugin use Chrome Custom Tabs to create a native experience inside the Flutter App.

QUESTION
UPDATE
I am trying to make an app using shiny
and DT
, similar to the accepted answer from Shree here. I would like, thou, to have the following additions to it:
- Extend the solution from Shree, so that items from the
DT
on the left (source) can be moved to more than one table on the right and back and be extensible, so that I can decide how many tables I want to put on the right. That is, different items from the table on the left can go in a different table on the right. - In addition, to have double arrow buttons next to each table on the right, so that all items in a table can be added or removed by click on the double arrow buttons, not only the single arrow buttons for moving just selected variables, like here, but still be able to decide whether to display them or not.
- Tables on the right to be visible even when empty.
Can someone help with these?
...ANSWER
Answered 2020-Jul-08 at 09:21To generalise to an arbitrary number of tables, I'd use a module. The module would contain the GUI and logic for a single DT
. It would have arguments for the "input DT" (the table from which rows are received) and the "output DT" (the table to which rows are sent). Either or both could be NULL
. The GUI would display the DT
and have a widgets to initiate the various "send rows" commands. See here for more details on modules.
As for your inability to remove rows from the source table: I'm not overly familiar with DT
, but I believe you need to use a proxy: as this page says "After a table has been rendered in a Shiny app, you can use the proxy object returned from dataTableProxy()
to manipulate it. Currently supported methods are selectRows()
, selectColumns()
, selectCells()
, selectPage()
, and addRow()
.".
QUESTION
I am programming a GUI Application to enter the height width and length of a workpiece. When the user clicks on the "Test" Button it should be warned (through a jlabel) if the fields are empty and if the input is bigger than 150. I am struggling with a problem here.The problem is that it works but there are a lot of warnings when I run the program according to the Numberformat. Also when I click the "Test" Button and the JTextfield are empty it does not show any warning but it just ignores this part of the code. How can I fix these problems? Is there a better way?

Answered 2020-May-19 at 18:05Not really and answer. More a critique of the code you posted.

QUESTION
I've been performing phylogenetic analysis in R for a while, employing libraries like ape, phangorn and phytools.
While solving a problem, I've come to a presence/absence data.frame that specifies if genes of interest belong (or don't) to a certain group.
An example of this would be:
...ANSWER
Answered 2019-Aug-18 at 19:35Here's a way using mixed integer programming approach. I am using ompr
for mathematical modeling and glpk
(free open source) as solver. Modeling logic is provided as comments in code.
I think the problem can be mathematically described as follows -
Filter dataframe to minimize number of rows such that sum of all columns is 1. Selected rows are called primary groups and every other row should be a subgroup of a primary group. A column (gene) can belong to only one primary group. Any unselected row is a subgroup of a primary group when
subgroup <= primary group
at all positions (columns). Therefore,(0,0,1,1)
is subgroup of(0,1,1,1)
but(1,0,1,1)
is not a subgroup of(0,1,1,1)
.
QUESTION
I'm trying to achieve a flexbox, where the row will have the titles all lined up. Requirements:
- The images won't always be the same height
- The description won't always be the same height
- The title could be 1 row, or 3 (depending on the length)
Here is a simple fiddle:

...ANSWER
Answered 2019-Jul-13 at 09:19you could look for a visual compromise.
flex children do not align with flex children from another flex parent.
You may try centering tex-info
and what-logo
and add an average min-height on .desc
