No such environment align

[ndthinh02]

hi, i have a latext string like this " \left[ \begin{align} & x=\frac{\pi }{4}+k\pi \ & x=\frac{\pi }{12}+k\frac{\pi }{7} \ \end{align} \right. " but when converting, it says no such environment align, so is there any way to fix it? thank you

Hello,

Use "aligned" environment instead of "align" environment.

This latext package depends on Flutter_math_fork library, and the "align" environment seems not supported in "flutter_math_fork" .

Use "aligned" environment like this:

$\begin{aligned}
  (a+b)^2 &= (a+b)(a+b) \\
  &= a(a+b)+b(a+b) \\
  &= a^2+ab+ba+b^2 \\
  &= a^2+2ab+b^2
  \end{aligned}$

Output:

The above code fail to run in Flutter 3.16 and Dart 3.2. What can I do to get it working

Finally got it to work by replacing \ with \cr as shown below \begin{aligned} (a+b)^2 &= (a+b)(a+b) \cr &= a(a+b)+b(a+b) \cr &= a^2+ab+ba+b^2 \cr &= a^2+2ab+b^2   \end{aligned}$
