LGTM once CI is re-enabled

@domesticmouse Thanks for the review and the tip about re-enabling CI. 👍
As this code fails on stable channel, can you explain me the expected process on flutter/samples for merging this PR? Do we have to wait for the next Flutter stable release before merging?

Yup, this PR will hang here until we have a new stable. I'll handle rolling this into a beta branch and then into stable.

Can you please update this PR, or give me access to do so? It has conflicts =(

I have updated the PR. FYI, I disabled master channel CI because there is a new breaking change in master and this PR is targeting beta channel.

[domesticmouse]

Please merge the latest from main. I'm preparing for a beta uber PR that this would be rolled into.

Integrated into #1556

[bleroux]

I have rebased this PR and updated it to comply with flutter/flutter#76072 (add an implementation for TextInputClient.didChangeInputControl).
I have also renabled CI on master because beta and master are aligned now.

[bleroux]

@domesticmouse This PR should be ok now on beta and master.

[domesticmouse]

Thank you, re-integrated into #1556 and now everything is green on beta and master. =)
